contour plot?

[carl]

In the help file it says:

"contour(Z) draws a contour plot of matrix Z, where Z is interpreted as
heights with respect to the x-y plane"

I have tried this:

Z = [2 3 3;
1 2 0];

[C,h] = contour(Z)
clabel(C,h);

which give me this:

But how does those line corresponds to elements in Z? From the help file its
supposed to mean the "heights" of Z but I don't understand this explanation.

Hi Carl, if you read the section in the MATLAB User's Guide called "The Contouring Algorithm", it explains exactly what it's doing. Look under User's Guide -> Graphics -> Creating Specialized Plots -> Contour Plots

Hope that helps,
