How to plot 2d filled contour

I have function y= (0.32/(0.32+0.38*x))^2

k=m*(dy/dx)

It means 'k' depends on 'm' and 'x'

x= 0:1 ( 0 to1)

m=0:1 ( 0 to1)

I want see variation of k with 'm' and 'x' using 2d contour in range of (0 ,1)

How to do it?

[KSSV]

x = linspace(0,1) ; 
m = linspace(0,1) ; 

[X,M] = meshgrid(x,m) ; 

Y = (0.32./(0.32+0.38*X)).^2 ; 
dX = gradient(X) ; 
dY = gradient(Y) ; 
K = M.*(dY./dX) ; 

contourf(X,M,K)
