Bug with max function

I found a strange bug in MATLAB 2012a.

I have a script with a matrix A (6000x1 double) and a matrix B (6000x1 double). When I try to use the following function by running my script file: max(A,B) I get the following error:

Error using max Matrix dimensions must agree.

However, when I perform the same operation in the command window, everything works fine.

What is wrong?

Does your script contain a variable called max?

Answer 1

[Azzi Abdelmalek]

Check in your script that A and B are the same size, in command windows type

size(A)
size(B)

Answer 2

[Matt]

Thank you for the answers guys.

No there is no variable called max.

Both matrices have the same size when entering what you told me Azzi: 6000 1.

And sorry I found the problem. The Answer turned out to be .....

The matrix B was originally taken from a structure, and even though I performed operations on that B matrix before arriving to that max operation, it kept the B matrix intact. Never mind, I just re-created the B matrix right before having to use the max function and it now works. Still strange.
