MATLAB: Matrix dimensions must be agree

error

Hello. I have a error about matrix dimensions and below is the code
clear all
n = 1100;
x = [randn(300, 1);
  randn(500, 1)+8.0;
  randn(300, 1)+12.0];
m = 3;
mu = linspace(min(x), max(x), m)';
tmp1 = (repmat(x, [m 1]) - repmat(mu, [1 n])).^2;
I have no idea about why this error is occurred because the size of matrix must be same. The error occurs in the final line.(tmp1=blah) How to fix it?

Best Answer

size( repmat(x, [m 1]) )
size( repmat(mu, [1 n]) )
on the command line will quickly show you the problem. The first is 3300 x 1, the second is 3 x 1100
