Hi everyone,
I don't know how to plot a multiple linear regression with 3 independent variables. Let say I have a function f(x,y,z) = 3x+4y+z. I would like 3 variables are on 3 axes and the result will be expressed by color scale. Anybody used to plot this kind of function, please help me.
Thanks much

You can use slice and contourslice to visualize 4D data. For example
[X,Y,Z] = meshgrid(-5:0.1:5);
C = 3*X+4*Y+Z;
figure();
slice(X,Y,Z,C, [-2 0 2], [], [-2 2]);
figure();
contourslice(X,Y,Z,C, -5:1:5, [], []);
view(3);
