I want to increase my matrix 13 rows to 50 rows with interpolation but not linear type. Could you help me?

Your matrix does not have 13 columns. it has 8 columns.
Decide whether you want to interpolate on rows or columns.
Decide what interplation type you want.
This is an example
A = [0.0 0.0 0.0 0.0 0.0 0.0890 0.2860 0.4380;
0.0177 0.0648 0.0888 0.1070 0.1640 0.3680 0.5720 0.7040;

B = interp1(1:w,A.',linspace(1,w,50),'cubic').'
