Error Message: "Incorrect dimensions for matrix multiplication."
Variables: X(5000 x 400) and theta (10 X 400);
Code: prob = X * theta';
This code works in the command window but when I try to run this segment of code in a script it gives me the shorten-error message above. Any suggestions on how to make the code run in the script?

dbstop if error
Then run your code. When it stops at that line,
size(X), size(theta)

Appears to work just fine. Do you define X or theta somewhere in your script with different dimensions? Perhaps clear your workspace?
X=rand(5000,400);
theta = rand(10,400);
prob = X*theta'
