Using custom colour with contourf

Hello,

I would like to use a custom colourmap 'mycmap' with contourf, how can I do this? I looked at previously asked questions and replies, but couldn't find anything which would help.

mycmap is a [64*3] matrix with values between 0 and 1. I tried [C,h]=contourf(dist_range,vel_range,capacity,14,'LineColor',mycmap'); and other ways, but couldn't succeed.

I found the answer. It was simply colormap(mycmap)

Thanks :)

See the below example:

[X,Y,Z] = peaks(100) ;
surf(X,Y,Z)
view(2)
shading interp 
% C = colormap ;
C = rand(64,3) ;
colormap(C)

I am using a random colormap in the above....it changes every time....You need to define your own C with your required colors...to get what you want...
