Red Blue Colormap

A colormap from bright blue, through white, and then to bright red.

Description

REDBLUE(M), is an M-by-3 matrix that defines a colormap.
The colors begin with bright blue, range through shades of blue to white, and then through shades of red to bright red. REDBLUE, by itself, is the same length as the current figure's colormap.

The function "colormapeditor" from MATLAB will be helpful to customizer the colormap

Thankyou: nice colormap. What do you think of this? A neater way to obtain c:

n = fix(0.5*m);
r = [(0:1:n-1)/n,ones(1,n)];
g = [(0:n-1)/n, (n-1:-1:0)/n];
b = [ones(1,n),(n-1:-1:0)/n];
c = [r(:), g(:), b(:)];
