I have one matrix A = [745 678]. I have another matrix B = [745 1].
I want to compute A / B. I want the result to be a [745 678] matrix. So basically every row in A (from 1 to 678) will be divided by the column matrix B. The end result will be all the matrix elements of A divided by the matrix elements of B.

In R2016b or later,
A ./ B
In earlier releases,
bsxfun(@rdivide, A, B)

Was able to figure it out by using the function repmat()

@Lane Dillon: repmat is most likely the least efficient method to solve the problem.

Is there a reason why you have not read the getting started tutorials? The manual is always a good thing to read.
C = A./B;
