I have a mesh that plots a terrain with values in a matrix Z(NxN), i need to color this whit the temperature value in every heigth set in another matrix with same length T(NxN) preserving the corresponding elevation.So my problem is that it only colors depending on the height.

Not sure if your plot is 3D or 2D. Maybe this will get you started (links below)
1. Which function did you use to produce the 3D plot?
2. I understand that you used array Z to produce the plot but you want the color scale to be based on another variable T, of equal size to Z. Is that correct? Could you provide the dimension of both variables just to confirm that?

% dummy data
[X,Y] = meshgrid(1:0.5:10,1:20);
Z = sin(X).*cos(Y);
T = X+Y;
% plot
surf(X,Y,Z,T)
colormap('hot')
colorbar
