4D plot - representing 3 variables function
显示 更早的评论
4D plotting:
I have 3 independent variables - x(1,n) , y(1,m) , z(1,l) - and I have matrix F(n,m,l) - 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?
(something like the picture shown here)

Where you able to find a solution? Would you share the code? I am in the same position.

Have you found any solution? I have the same question.

KSSV answer is still a 3D plot only.
You fix constant one of the x y z, replace the constant variable with the 4th variable and then plot for different constant values. Like taking photos.
Some people build a film for the sweep of a 4th variable.
may be you want to try this one
This is a Mathworks support team to a similar answer
Alternatively you build a custom 4D axis and try to 'see' 4D in 3D than can be messy but sometimes works, there is an explanation here
but a cube inside another cube is going to overlap data.
have fun

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

How to add function in this code. It looks independent of function.
