I am self teaching myself MATLAB so my apology if this is a very basic question. I want to use the function 'dir' to go into a folder and make a struct with only those files ending in '.xls' or '.xlsx'. Below is what I currently have and I would like to know how I can make it to also list '.xlsx' file in the same struct.
In addition, I would like to know where I can go to understand the nomenclature? of words like '%04df' and others.
xlsFiles = dir(fullfile(folderName, '*.xls'))
