Matrix Multiplication by a Scalar Please write a function calculate (matrix, scalar) that takes two arguments: a nested list that represents a matrix and an integer that represents a scalar. The function returns a nested list that corresponds to the result of matrix multiplication by a scalar. Your function should work with the following code: if __name__ == '__main__': scalar 3 A [[1,0,0], [0,1,0], [0,0,1]] D= calculate (A, scalar) assert D= [[3,0,0], [0,3,0], [0,0,3]] Save your function and the main code in a file called matrix.py and upload it here.

- Python problem Problem StatementDevelop a function that receives an array and returns a tuple with its dimensions. EntryMultiple lines, each line contains a list of numbers separated by a space and this line corresponds to a row in the matrix. At the end of the array, the character "*". DepartureThe dimensions of the matrix in a tuple, (m, n) where m are the rows and n the columns. If it is not a valid array, the word "Error" must be printed without quotes. Examples of Input example 1 8 4 3 2 6 9 7 14 4 1 2 5 6 1 31 1 2 2 3 4 5 60 3 4 6 0 2 4 8*Output example 1 (4, 8) Input example 2 1 6 8 9 5 4 1 2 5 4 8 25 3 5 6 9 8 2 9 6 3 4 66 2 4 8 6 9 1 0 3 61 2 3 4 5 6 7 8 9 1 1 2*Output example 2 ErrorPython please! Generalized image blender function Create a function blend images() which takes multiple RGB images as an input, and outputs a blended image. The function should accept following parameters 1. image list- A Python list of 3D arrays where each 3D array corresponds to an RGB image 2. weight list-A Python list of float values between (0, 1) corresponding to the pixel weight to be given to each image-e.g. [0.2, 0.3, 0.1, 0.4] for 4 images. The sum of the weights should be equal to 1. Test your function against a provided list of 5 images with following weight lists (i.e. 2 blended images) [0.2, 0.2, 0.2, 0.2, 0.2]- blend all 5 images [0.2, 0.3, 0.5]- blend first 3 images NOTE: DO NOT USE pre-existing image blending functions.C++ Sort a vector Define a function named SortVector that takes a vector of integers as a parameter. Function SortVector() modifies the vector parameter by sorting the elements in descending order (highest to lowest). Then write a main program that reads a list of integers from input, stores the integers in a vector, calls SortVector(), and outputs the sorted vector. The first input integer indicates how many numbers are in the list. Ex: If the input is: 5 10 4 39 12 2 the output is: 39,12,10,4,2, For coding simplicity, follow every output value by a comma, including the last one. Your program must define and call the following function:void SortVector(vector<int>& myVec) #include <iostream>#include <vector>using namespace std; /* Define your function here */ int main() { /* Type your code here */ return 0;} Enter program input - 5 10 4 39 12 2
- C language. Function write the arraylist_sort function This generic function sorts an array list using the given compare function. l An array list compare Pointer to the function which compares two elements If you cannot write down a generic function which works for all types, write down a function which sorts resturants. If you cannot use function pointers, you can write down multiple functions which sort using different criteria.Corner Case Write a function called corners that takes a matrix as an input argument and returns four outputs: the elements at its four corners in this order: top left, top right, bottom left and bottom right. (Note that loops and if-statements are neither necessary nor allowed as we have not covered them yet.) See an example run below: > [a, b, c, d] = corners([1 2; 3 4]) a = 1. 2 C = 3 4 Function e A Save C Reset MATLAB Documentation 1 Code to call your function e C Reset 1 A = randi(100,4,5) 2 [top_left, top_right, bottom_left, bottom_right] = corners (A) 3 B = [1; 2] 4 [top_left, top_right, bottom_left, bottom_right] = corners (B)Exercise 1: //The max function the max between a and b, it returns a if a == //b public double max(double a, double b); //The mult function returns the result of a * b public double mult(double a, double b); //The exist in array function returns the index of the element //‘a’ if //‘a’ exist in array ‘arr’ otherwise returns ‘-1’ public int existsInArray(int [] arr, int a); //Are array equals method compares two arrays and returns true // if the elements of array ‘a’ are equal to elements of array // ‘b’, element by element. If equals it returns 0, it returns - // 1 if not public int areArrayEquals(int [] a, int [] b); Devise four executable test cases for every method in the JUnit notation. See the attached handout for a refresher on the notation.
- Typedef struct Complex { Double a; Double b; } COMP_t, *COMP; -write a function which finds and returns the position of the complex number whose absolute value is maximum in a two dimensional array of complex numbers.Absolute value of z=a+bi is |z|=(a^2+b^2)^1/2/)9. Given an array of integers, write a PHP function to find the maximum element in the array. PHP Function Signature: phpCopy code function findMaxElement($arr) { // Your code here } Example: Input: [10, 4, 56, 32, 7] Output: 56 You can now implement the findMaxElement function to solve this problem. Keep it and.Exercise B: "Matrix Addition" For this exercise you will design and implement a function that takes two matrix arguments and computes their sum (if and only if a sum can actually be computed, returning an empty list otherwise). Two matrices can only be added together if they have exactly the same dimensions. If the dimensions are acceptable, then the matrix sum will have the same dimensions as either of the operands, and the value of each element in the matrix sum is itself the sum of the corresponding elements in the operand matrices. And although it does makes sense to test rectangularity before attempting addition, you need not perform this step (since you did it above). In order to complete this task, you will need to: ensure you know how matrix addition can be performed² ● Your submission for this exercise:
- C codeblocks Only write a function that receives an array, its size and a value to search for (define your function in the same way as the given function prototype). The function should return the index of the searched element in the array. If the element is not found, it should return -1. If the array has more than one element of that same value, it should return the value -2. The array is not necessarily sorted and should not be sorted in the function. #include <stdio.h>#include <stdlib.h>int searchIt(int arr[], int size, int value);int main() {int a[]={1,2,3,4,5};printf("%d", searchIt(a,5,3));return 0;}//Your answer starts here. For example: Test Result int a[]={1,2,3,4,5}; printf("%d", searchIt(a,5,3)); 2 int b[]={3,2,5,7,10,2,4}; printf("%d", searchIt(b,7,2)); -2 int c[]={-1,0,234,43,2,1,4,5}; printf("%d", searchIt(c,8,99)); -1Complete this code using Python m1 = [] #Matrix 1m2 = [] #Matrix 2#Write a function that will return the addition of Matrix A and B.#Create a new matrix C that will hold the addtion result of Matrix A and B (A+B).#Return the resultant matrix Cdef addMatrix(A,B):#Write your code here#Write a function that will return the subtraction of Matrix B from A.#Create a new matrix C that will hold the substraction result of Matrix B from A (A-B).#Return the resultant matrix Cdef subsMatrix(A,B):#Write your code here#Write a function that will return the multiplication of Matrix A and B.#Create a new matrix C that will hold the multiplication result of Matrix A and B (A*B).#Keep in mind,in order to perform matrix multiplication, the number of columns in Matrix A must be equal to the number of columns in Matrix B. #Return the resultant matrix Cdef multipyMatrix(A,B):#Write your code here#Write a function that will transform matrix A to the transpose of matrix A.#The transpose of a matrix means…Part 3 – Longest Common Sequence This part requires that you implement a C function that takes in as parameters two arrays and their sizes. This function is required to find the longest common sequence of numbers in these arrays. The prototype of the function MUST be: void longestMutualSequence (int firstArr[), int secondArr[], int sizeA, int sizeB); For example, if you have int a[] = {1, 2, 3, 4, 1000, 90, 100, 110, 200, 202}; and int b[] = {1, 1, 2, 3, 90, 100, 110, 200, 202, 600};, your function should output. Longest Common Sequence is 90, 100, 110, 200, 202. If there are two common sequences of the same size, your function should print out the first common sequence found.
