Write a function mymul.m' in Matlab which takes 2 matrices(vectors consider to be matrices) as inputs. Now you need to write your own code to do stan- dard matrix multiplication. For example, given two matrices A and B, 'my- mul(A,B)' is the same as A*B. BUT, remember all multiplication you used must be number-number multiplication, i.e. a number times another number. NO matrix-matrix, number-matrix multiplications are allowed. Create a 'HW2_1.m file. Write 'clear;clc' after your comments and then check your answer by using the following commands: M= floor( 20*rand(3) ); N= floor( 20*rand(3) ); P= floor( 20*rand(3,4) ); if ~(mymul(M,N)-M*N) disp('Good!) end if ~(mymul(M,P)-M*P) disp('Good!) end
