Hi,

code

UserData.matrix(1,1)=num2cell(sym(strcat('x','yz')))

is OK. But for code

UserData.matrix(1,1)=num2cell(sym(strcat('x','(','yz')))

I get error

Error using ==> sym.sym>convertExpression at 2547
Error: ')' expected [line 1, col 5].

Can you help me please?

Thanks

The error message is clear: The closing parenthesis is missing:

strcat('x','(','yz')
%  'x(yz'

Perhaps you need:

strcat('x', '(', 'yz', ')')

But it would be simpler to omit the strcat are insert 'x(yz)' directly.

I was thinking, that one char '(' is enough. Hmmmm. OK.

What happen if somebody will need something like that :-))) ?

But thanks a lot Jan
