Using strfind with inputs and outputs

The question is:

'write a function which takes as input a filename of the form name.asc and returns three new filenames, of the form name.mat, name.xls and name.jpg'

I know that I need to use the strfind function and replace the last three lettters using [], however I am not sure how to go about it.

See fileparts(): https://www.mathworks.com/help/matlab/ref/fileparts.html. It is easier to use for this question.

I am still not sure how to complete the question from this page.

For example

filename = 'name.asc';
[~,name,ext] = fileparts(filename)

Now you have 'name' and 'asc' in seperate variables. You can combine name with any extension you want.
