how to name matfile from variable name

I am trying to allow end users to name the .mat file that will save current settings as a preset.

What have tried so far is:

    presetName = inputdlg({'Enter a name for the Preset'},'Preset');
    %presetNameMat = strcat( presetName,'.mat'); 
    save('presetName');
    SaveUserSettings(handles);

Which saves everything in a file called presetName.mat - and not a .mat file named from the variable presetName. If I try and pass the value instead I get : Error using save Argument must contain a string.

This should work:

presetNameCell = inputdlg({'Enter a name for the Preset'},'Preset');
presetName = presetNameCell{:};
save(presetName);

You can of course combine them as:

save(presetNameCell{:});

I broke them out into separate lines so you can see how the code works.

Hi Kev111,

In your code, simply replace the line

 save('presetName');

with

 save(char(presetName));

and try..
