Hi folks,
I have the following code to save a table as an excel file. The problem is, the file is always saved to the default matlab path and not the user selected path.
Any ideas why this might be please?
FileName = uiputfile('*.xls','Save as');
data = app.CokeTable.Data;
columnName = {'Morphology','Counts', 'Percentages'};
rowName = {'Incipient','Circular', 'Lenticular','Ribbon','Isotropic','Filler','Resin','Total'}';
writecell(rowName, FileName, 'Range', 'A2:A9');
writecell(columnName, FileName, 'Range', 'A1:c1');
writematrix(data, FileName, "Range", 'B2:C9');

Always go directly to the documentation to understand the expected behavior of a function.
uiputfile returns up to 3 ouputs. The first is the filename and the second is the selected path.
Use [file,path] = uiputfile to store both the filename and path.
Then use fullfilepath=fullfile(path,file) to generate the full path to the file including the extension.
