i have 2d matrix with velocities in the range 4900-5100.I have problem with colormap.

function x=f(nd)

x=load('nd.dat') y=transpose(x) image(y) colorbar

Any suggestions regarding the range?

As a first attempt, try replacing

image

with

imagesc

which scales the colormap to the range of values in the matrix.
