Hello:

I am trying to use the pcolor command in Matlab but cannot figure it out. What I want to obtain is a grid system consisting of 8 equal rectangular areas, where each rectangle has a different color compared to the others.

Can someone please help me write the code for this?

Thanks,
Adam

Why don't you show us how you call PCOLOR and how you created the matrix
that you pass to PCOLOR?

I want to have node points on coordinates:
(0,0), (1,0), (2,0), (3,0), (4,0), (0,1), (1,1), (2,1), (3,1), (4,1), (0,2), (1,2), (2,2), (3,2), (4,2). I want the color between the nodes (0,0), (1,0), (0,1) and (1,1) to have color name = 1 and the next square having color name = 2 and so forth....

Well I am having difficulties defining the coordinates for the grid. This is what I have tried on just 4 squares which obviously is incorrect.

%%%%%%%%%%%%
clear, clc
x = [0 1; 0 1; 1 1; 2 2];
y = [0 0; 1 1; 0 1; 0 2];
z = [1 1; 1 1; 2 2; 2 2]; % color name
pcolor(x,y,z);
shading interp
%%%%%%%%%%%%

I think the problem is in the way I define the coordinates. Can someone suggest a better way of defining a 4 x 2 grid system with pcolor?
