Matrix Division: Different sized matrices

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.

Answer 1

In R2016b or later,

A ./ B

In earlier releases,

bsxfun(@rdivide, A, B)

My apologies, I made an error to the question. I just fixed it. I tried this but am still getting an error that: "matrix dimensions must agree."

Which MATLAB release are you using?

[Jan]

@Lane: Then please post the failing code. The suggestions of Walter and John do work:

A = rand(745, 678);
B = rand(745, 1); 
C = A ./ B;                  % >= Matlab R2016b
D = bsxfun(@times, A, B);    % All Matlab versions

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;
