Bone colormap array
c = bone
c = bone(m)
c = bone returns the bone colormap as a
three-column array with the same number of rows as the colormap for
the current figure. If no figure exists, then the number of rows is
equal to the default length of 64. Each row in the array contains
the red, green, and blue intensities for a specific color. The intensities
are in the range [0,1], and the color scheme looks like this image.
Plot a surface and assign the bone colormap.
Get the bone colormap array and reverse the order. Then apply the modified colormap to the surface.
c = bone; c = flipud(c); colormap(c);
Get a downsampled version of the bone colormap containing only twenty colors. Then display the contours of a paraboloid by applying the colormap and interpolated shading.
c = bone(20); [X,Y] = meshgrid(-10:1:10); Z = X.^2 + Y.^2; surf(X,Y,Z); colormap(c); shading interp;
