csvwrite with a double

Hello I am having a great deal of difficulty writing a 512 x 1 cell array of type double in a .MAT file to excel I tried this:

exportlist = get(handles.listbox2,'string')

%we need to change the directory to the chosen output and after we have %re-loaded the .mat file into the workspace convert the files %The evalin evaluates the expression in 'base' or workspace

for a = 1:length(exportlist) outloc =get(handles.CSV_file, 'string'); cdstring = ['cd(''' outloc ''')']; eval(cdstring); csvwrite([exportlist{a},'.csv'],evalin('base',cell2mat(exportlist{a})))

end

No dice. The error I get is this:

??? Cell contents reference from a non-cell array object.

Error in ==> cell2mat at 44 cellclass = class(c{1});

Error in ==> MAT_to_Csv>convert_button_Callback at 319 csvwrite([exportlist{a},'.csv'],evalin('base',cell2mat(exportlist{a})))

Thanks

Bill

No. Your line probably should be:

csvwrite([exportlist{a},'.csv'],evalin('base',exportlist{a}))

Read my answer to your other question. I think you should really consider the dynamic field names like Vars.(exportlist{a}) to avoid using eval().

Your eval(cdstring) could be replaced by cd(outloc)

Yes, yes, dynamic field names! And pass the structure in as a parameter or work with in via handles, so that you do not need to use evalin()

I would also add the precautionary measure of using

exportlist = cellstr(get(handles.listbox2,'string'));
