Hellow, i need code for visualtisation for a 2D mesh. I have a matrix with grey values ( 0 to 1) and i have to visualate it according to the grey value. For example a 3x3 matrix [ 0.236 0.256 0.785 ; 1 0 0 ; 0.369 0.259 0 ] and know i want to see where the most grey is in a mesh. Hopefully anyone can help me. Thx

The commands image and surf might be useful here.
Or, you can try using the plot selector to interactively find a type of plot that is right for your data.

Just type this: surf(peaks(30)), colormap('Gray');
