4D plotting:
I have 3 independent variables - x(7x8x61) , y(7x8x61) , z(7x8x61) - and I have matrix F(7x8x61) - corespond to every value of [x,y,z].
How can I represent F on a 3D grid?
Maybe with a surface, where F values represented in color? (like in the example below)

clc; clear
[X,Y,Z] = peaks(100);
C = rand(size(Z)) ;
figure
surf(X,Y,Z,C);
colorbar

Visit that link. On the upper right hand side, click on "Download the ZIP file". Save the .zip and unzip it into a convenient directory that is not underneath the MATLAB installation path. Now use pathtool in MATLAB to add that directory to your MATLAB path. You will then be able to use the function.
