Syntax

ezcontourf(f)

ezcontourf(f, r)

ezcontourf(f, a)

ezcontourf(f, r, a)

Generates a contour plot with intensity shading of a function of two variables. ezcontourf plots f over the specified region.

Name	Description
f	Specifies the function you want to plot. f is a string that represents a function of two variables. If f is a single expression of two variables x and y, ezcontourf plots the contour of z = f(x, y).
r	Specifies the region of the plot. r is a four-element real vector or a two-element real vector. If r is a four-element vector, the r values represent [xmin, xmax, ymin, ymax]. If r is a two-element vector, the r values represent the square [xmin, xmax, xmin, xmax]. The default is [-2pi, 2pi, -2pi, 2pi].
a	Specifies the grid size. a is a positive integer. LabVIEW uses a grid of a-by-a points. The default is 60.

This function is not supported in the LabVIEW Run-Time Engine. This function can remain in your scripts when you build a stand-alone application or shared library, but the LabVIEW Run-Time Engine does not execute this function.
