Hello,

I want to plot the isolines of an unknown function of 2 variables (z = f(x,y)).
The only information available about this function is a set of values of the form:

x1 y1 z11
x1 y2 z12
....
x1 yN z1N
x2 y1 z21
x2 y2 z22
x2 yN z2N
....
xN yN zN

How can I plot the isolines of this function?

Thanks in advance for any help.

help griddata - if the data are randomly spaced in x and y
help contour
