hi all ,
got a problem with my code and i'm using matlab.
surf (X, Y , abs(H));
the problam is that it gives me a graph that is black! no colors... and i know that the default is random colors but i get only black from some reason.
the other problem is that i suppose to write y=-100:0.1:100; and not -60:0.1:60; but it will not work if i try value 100. i have no idea how to fix it
