Hi Julio,

Thanks for the feedback.

It seems you have installed Maple and the Maple sym function is called instead of the MATLAB one.
Can you try "u = sym('u',[4,1])" in MATLAB and see if u is a 4x1 vector?

Look forward to your response.

Hi Julio,

Thanks for the response.

It seems that the sym function didn't return the right result (4x1 vector) because of the bug caused by the Maple sym function.

I have updated the source code to guard this and the problem might have been solved .
Alternatively, you can call the Matlab sym function rather than the maple one by removing the maple path from MATLAB search path.

I hope this could solve the problem.
Thank you.

Hi,
Thank you for your response. Here is the Matlab console give after the command you told me before :

u = sym('u',[4,1])

u =

                           [u1, u2, u3, u4]

Thank you in advance,

Hi Deng,
In fact as you said before, the problem was the symbolic Maple toolbox. So, I uninstalled the toolbox and that's it. Right now is working.
Thank you so much for your help

Best regards,
