Use the size function to get the dimensions. There are other functions in and at the end of the size documentation that can provide you with similar results.
To use the results, assuming ‘A’ is your array, to index the the rows:
r_idx = 1:size(A,1);
and the columns:
c_idx = 1:size(A,2);
and other dimensions as necessary.

Do not use importdata. Use readtable
