Recall that if a is an m × n matrix and b is a p × q matrix, then the product c = ab is defined if and only if n = p, in which case c is an m × q matrix. (a) write a function m-file that takes as input two matrices a and b, and as output produces the product by columns of the two matrix. for instance, if a is 3 × 4 and b is 4 × 5, the product is given by the matrix c = [a*b(: ,1), a*b(: ,2), a*b(: ,3), a*b(: ,4), a*b(: ,5)] this content is protected and may not be shared, uploaded, sold or distributed 2019 v3 copyright@ school of mathematical and statistical sciences, arizona state university 8 the function file should work for any dimension of a and b and it should perform a check to see if the dimensions match (hint: use a for loop to define each column of c). call the file columnproduct. m. test your function on a random 3×2 matrix a and a random 2×5 matrix b . compare the output with a*b. repeat with 5 × 3 and 3 × 4 matrices and with 5 × 3 and 4 × 3 matrices. use the command rand to generate the random matrices for testing. include in your lab report the function m-file and the output obtained by running it
