Where is the problem 2

Hi,

where is the problem

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

???

[Walter Roberson]

Why the heck is the "sym" in there ??

[John Petersen]

One too many parentheses ). Take one off.

Witch one?

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

[John Petersen]

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().

[john]

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'

[John Petersen]

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.

[john]

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;

[john]

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...:-(

[john]

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

[John Petersen]

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.
