Load real number, not integer

Hi,

why is not possible to load real number? For example "3.14"???

It works only with integer.

 UserData.matrix(1,1)=num2cell(sym(char(strcat('_',get(handles.a,'String'),char(sym(UserData.matrix{1,1}))))));

Can you help me?

What exactly does "load" mean here and where does the 3.14 appear in the posted code?

Sorry...I changed the code.

From edit text "a" a want load real number and than save into matrix.

I use matrix forexample for saving informations into folder,

The question is still not clear. Why do you add a leading underscore? Why do you make the expression symbolic? You can save informations to a folder, but to a file only. But even then it is not clear, how the extraction of the cell element UserData.matrix{1,1} is related to a loading.

So I try to guess a solution, but thuis does not match to your posted code in any way.

From the text of your question, I'd extect this could be a solution:

UserData.matrix{1,1} = sscanf(get(handles.a, 'String'), '%g');

Hi,

UserData.matrix is matrix of type cell. I store in this matrix many informations, real numbers, characters, strings.

I try to save into cell UserData.matrix{1,1} real numbers. I want to store in this cell {1,1} more numbers, not only one. My idea was to use underscore to devide individual numbers. Therefore I used strcat- for connecting new and old numbers.

And also I need store into UserData.matrix{1,2} strings. These strings have to be also devided from each other.

And also than I need get back individual numbers, strings

For saving matrix I use this code:

cm=size(UserData.matrix);
for i=1:cm(1);
   for j=1:cm(2);
        data(i,j)=sym(UserData.matrix{i,j});
    end;
end;

   vys=size(data);
   for i=1:vys(1);
       for j=1:vys(2);
           vysledok(i,j)=cellstr(char(data(i,j)));
       end;
   end;          

   UserData.save=vysledok;
   data=UserData.save;
   save(fullfile(PathName, FileName), 'data');

Please do not use "save" for storing variables in a cell. "save" usually means writing to disk.

It is unclear how and underscore should help to store numbers in a cell. This does not sound like Matlab.

Perhaps this helps:

M = cell(2, 2);
M{1,1} = 3
M{1,1} = [M{1,1}, 4];
M{1,1} = [M{1,1}, 5];
M{1,2} = {'1st string'};    % A nested cell!
M{1,2}{2} = {'2nd string'}; % Nested cell indexing!

disp(M{1,1})
disp(M{1,2})

Hi,

I use save, cause I want a write it on a disk....

Based on underscore I can find out and divide each numbers.

I changed code:

UserData.matrix{1,1}=sscanf(strcat('||',get(handles.a, 'String'),char((UserData.matrix{1,1}))), '%s');

vys=size(UserData.matrix);
for i=1:vys(1);
    for j=1:vys(2);
        vysledok(i,j)=cellstr(char(UserData.matrix{i,j}));
    end;
end; 

   UserData.save=vysledok;
   data=UserData.save;
   save(fullfile(PathName, FileName), 'data');

And it looks like it works....I have to test it now.....

[Jan]

I cannot imagine what the conversions in these two lines should do:

UserData.matrix{1,1}=sscanf(strcat('||',get(handles.a, 'String'), ...
                            char((UserData.matrix{1,1}))), '%s');

vysledok(i,j)=cellstr(char(UserData.matrix{i,j}));

I have the strong impression that this can be done much more direct, but when it works as expected, who cares.
