How i generate two dimensional membership function and plot it?

i have tried 1D membership function and plot it. like trapezoidal, gaussian, bell etc. these are one dimensional. for example

x=0:.1:100; y=trapmf(x,[10 30 56 78]); plot(x,y);

to generate and plot 1D trapezoidal membership function

hi,

there are many ways , you can find them in Tutorials...but for fast way :

 x=0:0.1:10;
y=trapmf(x,[1 5 7 8]);
z=y'*y;
