F = [ (pi-1); 0] % work
F = [ pi -1; 0] % don't

Break down the big expression in smaller one. That makes your code much more visible and easy to maintain.

And second advise: When programming, always check individual function works before putting them together. In your case you seem never check F alone.

Dear Bruno,

Can you maybe explain what you mean by " Here the parse interpret as 2-column."

Thanks again.

Best wishes

Sorry for the typo , should read "Here the parser interprets as 2-column."

Think about the examples I gave:

F = [pi -1;
0]

F = [(pi -1);
0]

Wow Bruno, this did the trick. It solved all my 7 variables in once.
Thanks again.
