How to write a function that imports data from an xlsx file

I need to write a function that imports an .xlsx file and saves the data as .mat file. I need to call this from the command line. I am so confused on how to do this

Why write your own function? In MATLAB, you would use readmatrix or readtable.

Once your data is loaded, use the save function to save your variable(s) to a mat file.

xlsread is not recommended.
