I have data in matrix format. The values vary within a finite range.
I would like to generate a 3-D smoothed contour plot, except that I want the regions of equal values values identified and colored in the same color.
What I have is a matricx of efficiencies, I want to identify the region where the efficiencies are above 95%, between 95% and 90%, and so on.

This seems to do what you want:
x = linspace(-5,5);
[X,Y] = meshgrid(x);
M = exp(-(X.^2+Y.^2)/10);
figure(1)
surf(M)
grid on
colormap(jet(20))
colorbar
with ‘M’ the matrix to plot.
It produces:
