MATLAB: Where is the problem 2

strcat

Hi,

where is the problem

UserData.matrix(1,2)=num2cell(sym(char(strcat(get(handles.edit7,'string'),',',get(handles.edit6,'String')))))

???

One too many parentheses ). Take one off.

You don't need the switch and cases. Just use

a1 = str2double(str{val});
b1 = a1;

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.
