## Syntax

plotf_mesh(f)

plotf_mesh(f, r)

plotf_mesh(f, a)

plotf_mesh(f, r, a)

plotf_mesh(f, 'circ')

plotf_mesh(f, r, 'circ')

plotf_mesh(f, a, 'circ')

plotf_mesh(f, r, a, 'circ')

Legacy Name: `ezmesh`

## Description

Plots a function of two variables as a 3D mesh surface. You can write the function in explicit or parameterized notation. plotf_mesh plots f over the specified region.

Examples

## Inputs

Name Description
f Specifies the function you want to plot. f is a string or three strings separated by commas. Each string represents a valid expression. If f is a single expression of two variables x and y, plotf_mesh plots z = f(x, y). If f is a set of three strings that share the same two variables, LabVIEW displays a parameterized surface.
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.
'circ' Changes the specified region of the plot from a rectangle to a disc. The center of the disc coincides with the center of the underlying region specified by r.

## Examples

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

plotf_mesh('sin(sin(t*t))*cos(s)', 'sin(sin(t*t))*sin(s)', 'cos(s)')

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

plotf_mesh('s', 't', 's+t', 20, 'circ')
