4.1 Write a function called "checkmat evenodd that will receive a matrix (for example, mat) as an input argument, and return a new matrix (same size with the input matrix) using nested for loops. If the element in the input matrix is an even number, then the corresponding element in the new matrix is 0; otherwise, the element in the new matrix is 1. Also, write the block comment "This function check the even/odd number of a matrix." See below example: outmat 1 -2 34 5 6 7 8 9 -10 -12 4.2 Generate a random 3-by-5 integer matrix called "mat code, for example: [ out mat ] = checkmat-even-odd( mat) in the range [-10, 10], and test your
