Q:

How to prove a number is a Multiple of an integer in MatLab? 

How can we prove a number if it is really a multiple or divisible by an integer, WITHOUT using mod() and -rem() in MATLAB?  

A:

Use ROUND:
% To determine if i0 is a multiple of i1:
is_multiple = ( i1 * round(double(i0)/i1) == i0 );
