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

Help, I need insert sym string into cell matrix, sym string I created from 2 edit boxes, and between them is one "," or another char

nevermind, you have the right number of parentheses. What is sym?
why are you using num2cell? You don't have any numbers, just strings. If the strings are numbers you need to convert them using str2double().

this code works :
UserData.matrix(1,2)=num2cell(sym(strcat('a',get(handles.edit7,'String'),'xx',get(handles.edit6,'String'),'xx',num2str(si_co_val))));
but this no, why?:
UserData.matrix(1,2)=num2cell(sym(strcat(get(handles.edit7,'String'),'xx',get(handles.edit6,'String'),'xx',num2str(si_co_val))));
different is only 'a'

What error are you getting? Split the code into different lines so you can see which parts are working. I suspect it's a problem with sym(), since I don't know what that is doing.

this is error:

Please break up the code
str7 = get(handles.edit7, 'String');
str6 = get(handles.edit6, 'String');
strsi = num2str(si_co_val);
symstr = strcat(str7, 'xx', str6, 'xx', strsi);
disp('symstr =')
symstr
assym = sym(symstr);
disp('assym =')
assym
ascell = num2cell(assym);
disp('ascell =')
ascell
UserData.matrix(1,2) = ascell;

there is the same fault. But I put into UserData.matrix(1,1)...there is no fault for plus value for example 7, but I got error for minus value for example -7...:-(

I modified code in this form
UserData.matrix(1,1)=num2cell(sym(char(strcat(get(handles.edit5,'string'),'_',char(si_co_str{si_co_val}),'_',char(get(handles.edit6,'String'))))))
When I enter into edit6 number 5.4, than I got in matrix 54. But I need number 5.4....how can I solve that?
Please for help

Please break up the code like this
a1 = get(handles.edit6,'String');
a2 = si_co_str{si_co_val};
a3 = get(handles.edit5,'string');
a4 = strcat(a3,'_',char(a2),'_',char(a1));
a5 = sym(char(a4));
UserData.matrix(1,1)=num2cell(a5);
Then perhaps we can see what's going on.
