How do I load .mat file and take certain columns and make them an array?

Hi, I have a .mat file with many columns but I only need 3 of them. How do I take each column and make it into an array?

You could do it with matfile(), as in this example:

You cannot access the variables of a table from a .mat file without loading the entire table.
