MIR Toolbox data in classification learner

Hi all,

I'm totally new to Matlab and have spent a few days looking for good examples online but haven't found anything clear enough. I am extracting features such as rms and mfcc from some sound files and would like to use the data to develop a classification learner. I am not sure how to put MIRtoolbox data into a table or matrix in Matlab so that I am able to open it in the Classification Learner app- is anyone able to clarify? I previously only practiced by copying the extracted numerical data into an Excel document, but that is not the most streamlined option, of course.

Any help would be appreciated, thank you!
