Owning Class: plots

Requires: MathScript RT Module

## Syntax

plotf_contour(f)

plotf_contour(f, r)

plotf_contour(f, a)

plotf_contour(f, r, a)

Legacy Name: `ezcontour`

## Description

Generates a contour plot of a function of two variables. plotf_contour plots f over the specified region.

Examples

## Inputs

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, plotf_contour 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 [-2*pi, 2*pi, -2*pi, 2*pi].
a Specifies the grid size. a is a positive integer. LabVIEW uses a grid of a-by-a points. The default is 60.

## Details

The following table lists the support characteristics of this function.

 Supported in the LabVIEW Run-Time Engine No (always ignored) Supported on RT targets No

## Examples

f = 'sin(x)*cos(y)';
plotf_contour(f)

f = 'a^4+b^2-1';
r = [-2, 2, -3, 1];
plotf_contour(f, r)
