Problem when using imwrite ...

%The directory where the image will be saved

folder = '\Users\public\Documents\MATLAB\faceBank';          
name = strcat(Rnombre,Rapellido,Rcargo,'.jpg');

%Are attributes of which the file name will be composed

imwrite(work_area,fullfile(folder,name));
work_area is the variable that contains the image

i have this error

Error using imwrite>parse_inputs (line 510)
A filename must be supplied.

Error in imwrite (line 418)
[data, map, filename, format, paramPairs] = parse_inputs(varargin{:});

In your

strcat(Rnombre,Rapellido,Rcargo,'.jpg')

I suspect that one of those variables is a cell array instead of a character vector.

Also if one of them is numeric then you would need to cross check whether the results would be char or numeric. Do not use strcat to try to insert numeric values into a character vector: see sprintf() or num2str for converting numeric to characters.

I get the data in this way, it is assumed that they are already of the "String" type

try with num2str () and sprintf () but it did not work.

if I write the address of the direct file, it works (but it's not what I need)

Rnombre = get(handles.nombreM,'String');
  Rapellido = get(handles.apellidoM,'String');   
  Rcorreo = get(handles.correoM,'String');
  Rcargo = get(handles.cargoM,'String');

[Walter Roberson]

If one of those is a handle to a uicontrol style edit or text for which Max has been set to more than 1, or if one of them is a handle to a uicontrol style push or pop, then get() of the String will return a cell array of character vectors rather than a character vector.

You should use class() to test each of those variables.

Try

Rnombre = char(handles.nombreM.String);
Rapellido = char(handles.apellidoM.String);   
Rcorreo = char(handles.correoM.String);
Rcargo = char(handles.cargoM.String);

Thanks, it worked!
