MATLAB: 3d point colouring – 21 by 21 by 21 matrix

3dfieldMATLABplot

Hi,

I have a matrix 21 by 21 by 21. I need to do a "field plot" of this matrix, in which the matrix index defines the position & the value of the matrix element defines the point colour.

Any suggestions how to do this?

Thanks in advance.

Regards,

What about something like slice?

E.g., a basic outline:

M = number of rows
N = number of columns
result = zeros(M,N);  % pre-allocate result
for n=1:N
    for m=1:M
        result(m,n) = whatever;  % insert your calculation code here
    end
end

[x1, x2] = meshgrid(-.5:0.05:0.5, -.5:.05:.5);
x1dot = - x1; 
x2dot = 2*x2;
quiver(x1,x2,x1dot,x2dot)
hold on
starty = -0.5:0.05:0.5;
startx = ones(size(starty))*-0.5; %specify the starting x values- LHS
streamline(x1,x2,x1dot,x2dot, startx,starty)
startx_2 = ones(size(starty))*0.5; %specify the starting x values -RHS
streamline(x1,x2,x1dot,x2dot, startx_2,starty);
