I am tring to use the read matrix and split the data into 4 different values, I want the variables to be, for example, [row 1, row 5, row 9, row 13, row 17, etc...]. I would like it to skip 4 rows in between each value taken if that is possible.

Try this:
m = readmatrix(filename);
[rows, columns] = size(m)
% Split into 4 matrices
m1 = m(1 : 4 : rows, :);
m2 = m(2 : 4 : rows, :);
m3 = m(3 : 4 : rows, :);
m4 = m(4 : 4 : rows, :);
