PythonCompose a module matrix.py that implements the following API for vectors and matrices ### Matrix Module APIBelow is a detailed listing of function calls available in the `matrix.py` module with their respective descriptions:| **Function Call** | **Description** ||-------------------|-----------------|| `rand(m, n)` | Generates an m by n matrix containing random floats between 0 and 1. || `identity(n)` | Produces an n by n identity matrix. || `dot(v1, v2)` | Computes the dot product of vectors v1 and v2. || `transpose(m)` | Returns the transpose of the matrix m. || `add(m1, m2)` | Calculates the sum of matrices m1 and m2. || `subtract(m1, m2)`| Computes the difference between matrices m1 and m2. || `multiplyMM(m1, m2)` | Produces the product of matrices m1 and m2. || `multiplyMV(m, v)` | Returns the matrix-vector product of matrix m and vector v (result is a vector). || `multiplyVM(v, m)` | Computes the vector-matrix product of vector v and matrix m (result is a vector). |This API is designed to facilitate operations on vectors and matrices for educational and computational purposes.**Section Reference:** For more information on how these functions can be applied, refer to Section 1.4.

Since multiple function calls have been asked to be implemented at a single request, we will answer first four function calls in “matrix.py” module. If you want any other function call to be implemented, kindly post the question separately.Module "matrix.py": import random import numpy #Function to print m-by-n matrix containing random floats between 0 and 1 def rand(m,n): matrix=[] matrix.append([]) for r in range(m): for c in range(n): x = random.uniform(0, 1) print (x,end= " ") print() #Function to print n-by-n identity matrix def identity(n): for r in range(n): for c in range(n): # Here end is used to stay in same line if (r == c): print("1 ", end=" ") else: print("0 ", end=" ") print() #Function to find the dot product of two vectors def dot(v1,v2): print(numpy.dot(v1, v2)) #Function to print transpose of matrix m def transpose(m): re = [[0 for x in range(len(m))] for y in range(len(m[0]))] for i in range(len(m[0])): for j in range(len(m)): re[i][j] = m[j][i] for i in range(len(m[0])): for j in range(len(m)): print(re[i][j], " ", end='') print() m=2 n=2 print("rand(m,n) ") rand(m,n) print("\nidentity(n)") identity(n) print("\ndot(v1,v2) ") v1 = [[2, 1], [0, 3]] v2 = [[1, 1], [3, 2]] dot(v1,v2) print("\ntranspose(m) ") m = [ [5, 6, 5, 7], [2, 3, 2, 3]] transpose(m)Module "matrix.py": Screenshot #1: Screenshot #2:

Structural Verification Structural verification is, in this case, validating that a data structure is formed according to its specification. For this lab you are given an essentially arbitrary specification, but you could think of this being used to verify a data structure produced by a program that must have certain properties in order to be used correctly. For example, a list must not be circular, or an image file might require a particular header describing its contents. You must implement this function, which examines a matrix and ensures that it adheres to the following specification: bool verify_matrix(int x, int y, int **matrix); This function accepts an X dimension, a Y dimension, and a matrix of y rows and x columns; although it is declared as int **, this is the same type of matrix as returned by parse_life() in PA1, and you should access it as a two-dimensional array. Note that it is stored in Y-major orientation; that is, matrix ranges from matrix[0][0] to matrix[y 1][x -…

Write a Python code for array in numpy to create Python Matrix
in c++ using 2D Arrays The following diagram represents an island with dry land (represented by “-“) surrounded by water ((represented by “#“). ##-########## #-----------# #-----------# #------------ # -----------# #------X----# #-----------# ############# Two bridges lead off the island. A mouse (represented by “X”) is placed on the indicated square. Write a program to make the mouse take a walk across the island. The mouse is allowed to travel one square at a time, either horizontally or vertically. A random number from 1 to 4 should be used to decide which direction the mouse is to take; for the sake of uniformity assume that 1 = up, 2 = down, 3 = left, and 4 = right. Since the mouse is wearing cement mouse galoshes, the mouse drowns when he hits the water. He escapes when he steps on a bridge. You may generate a random number up to 100 times allowing the mouse to take 100 steps. If the mouse does not find a bridge by the 100th try, he will wither away and die of starvation.…
