Hi all! I'm very, very new to Matlab.
With that said, does anyone know how to convert a CSV file into a .mat file in the MATLAB environment? I've had a lot of trouble answering this question.
I attached a CSV file I'd like to convert as an example.
Thank you!

Use READMATRIX and SAVE. If you don't know what options you have for file import/export, start here:

Ran in:
Since the csv only contains numeric data, use readmatrix to load the data in a variable
variablename=readmatrix('s1.csv')
variablename = 601×30

use Readtable function or readmatrix if your data includes numeric
loadyourfile=readtable("s1.csv");
save('yourmatfile.mat','loadyourfile')
