MATLAB:

you are prohibited from using explicit loops (i.e., for-loop or while-loop). You must use logical indexing instead. Note that an ifstatement is not a loop and can be used in your solution. Write a function called problem5 that takes an at most two-dimensional matrix A as its sole input. The function returns a row vector v containing all elements of A that are prime numbers. The elements of v are stored according to row-major ordering of A. You are allowed to use the isprime built-in function.
