Java Program Your program should use 2D arrays to implement simple matrix operations. Your program should do the following: • Read the number of rows and columns of a matrix M1 from the user. Use an input validation loop to make sure the values are greater than 0. • Read the elements of M1 in row major order • Print M1 to the console; make sure you format as a matirx • Repeat the previous steps for a second matrix M2 • Create a matrix M3 that is the transpose of M1 and print it to the console • Check if M1 and M2 can be added (should have the same dimensions). If possible, add M1 and M2 and print the result to the console. Otherwise print an error message. • Extra credit: Multiply M1 and M2 if possible and print to the console. If the matrices cannot be multiplied, print an error message. Implementation requirements: • Use a helper method for reading a positive integer using an input validation loop. • Use a helper method for printing a matrix. Your helper methods should be private and…

NumPy includes a submodule numpy.linalg where many functions are defined to allow the user to do various things related to linear algebra. If A is a square matrix represented as an object of type ndarray , the function eigvals () will return the eigenvalues of A as an array. Which of the following code snippets would correctly import the module and call this function with the matrix (A as input? Note: There may be more than one correct answer! Select all that will work.

A left rotation operation on an array of size n shifts each of the array's elements 1 unit to the left. Given an integer, d, rotate the array that many steps left and return the result. Example:d=2arr=[1,2,3,4,5] After 2 rotations, arr'=[3,4,5,1,2]. Function Description: Complete the rotateLeft function in the editor below. rotateLeft has the following parameters: 1. int d: the amount to rotate by 2. int arr[n]: the array to rotate Returns 1. int[n]: the rotated array Input Format: The first line contains two space-separated integers that denote n, the number of integers, and d, the number of left rotations to perform.The second line contains n space-separated integers that describe arr[]. Constraints: 1. 1<=n<=10^5 2. 1<=d<=n 3. 1<=a[i]<=10^6
