Syntax

Cmapped=cmaperise(C,cmap,clim);

Description

This function creates RGB colors for the data C using the colormap cmap and the limits clim.

Examples

[X,Y,Z]=peaks(50);
[F,V,C]=surf2patch(X,Y,Z,Z);

clim=[min(C(:)) max(C(:))];

%RGB color set with map 1
cmap=viridis(250);
C_rgb_1=cmaperise(C,cmap,clim);

%RGB color set with map 2
cmap=gray(250);
C_rgb_2=cmaperise(C,cmap,clim);

%RGB color set with map 3
cmap=gjet(250);
C_rgb_3=cmaperise(C,cmap,clim);

Visualize

% Offset coordinates so plots are side by side
V2=V;
V2(:,1)=V2(:,1)-min(V2(:,1))+max(V(:,1));
V3=V2;
V3(:,1)=V3(:,1)-min(V3(:,1))+max(V2(:,1));
