Hello, I am a beginner at Matlab. I would like to create contourf plot. The plot size is pixel by pixel, and the grey level from 0-192. The code as below,
r_M = [4.76083603812144 4.59732757325507 3.84078375990161 2.83522761891933 2.03979313208838 1.61429885435575 1.58483400872700 2.07651813385661 2.55722735199852 2.72392206632444 2.93752535716962 3.36165244504211 4.22402540734126
