How to give a name to xlswrite with a dialogue box? (gui)

Let say i have an matrix M. Then i want to make a excel file which contain this matrix M. The things that i usually use is a kind of static and manually with: xlswrite('test.xls',M).

I don't know how to make a flexible one. What I mean is, when i click "save" in my GUI figure, there'll some kind of dialogue box appear then i will give the name of it's excel file.

What to do? Thanks before :')

Use uiputfile() to get a target file name and target directory. Use fullfile() to splice the two name parts together to get a complete pathname. Pass that pathname to xlswrite()

could you give a kind of example how to use uiputfile(), fullfile()?

[Walter Roberson]

[filename, pathname] = uiputfile('*.xls', 'Choose a file name');

outname = fullfile(pathname, filename);

xlswrite(outname, M);
