Matrix dimensions must agree.

I am trying to multiply the same matrix by the transpose of itself and it is giving me the error of matrix dimensions must agree. Code: XX=X.*X';

Answer 1

Try using * instead of .*

[mike moran]

that will not work because X is a matrix of 135x100, therefore would need to use element by element multiplication.

Have you tried it?

[mike moran]

I figured it out. My matrix was in uint8 and it needed to be in double.
