Question

I am trying to figure out how to generate a colored chart on a matlab, like the one you can find in here on page 9. (You will have to look through it to find what I am referring to – Stackoverflow doesn’t allow me to post pictures in the postings just yet.)

A few questions:

1. I do have the table, but my table is a set of discreet points, not a continuous spectrum. So… can I do it in the first place?

2. If it IS possible, how would I do it?

(By the way, that table is from combat simulation for Risk – I am doing the combat simulation for Risk II, just for fun.)

Answer 1

The type of image you are looking for, as can be seen on Page 9, is a imagesc plot. Here’s a simple example, using a double sin function. Done without vectorization for simplicity.

x=0:pi/180:pi;
y=0:pi/180:pi;

output=zeros(length(x),length(y));
for ix=1:length(x)
   for iy=1:length(x)
      output(ix,iy)=sin(x(ix)*2)*cos(y(iy)*4);
   end
end
figure;imagesc(x,y,output)
