MATLAB: Save figure with a specific name

Question

Hello,

I export data using the following code :

[file,filepath,filter] = uigetfile({'*.xlsx'},'Select your data');
filename = fullfile(filepath, file);
[data] = xlsread(filename);

I use the data to generate a figure .png and I save it using "saveas".

h=figure('Color',[1 1 1]);
...
saveas(h,'FIG','png');

How can I automatically save the figure with the same name of the selected file with uigetfile?

Thank you!

[filedir, basename, ext] = fileparts(filename);
newname = fullfile(filedir, [basename '.png']);
saveas(h, newname, 'png');
