Description

Plots a function of two variables as a 3D surface in conjunction with contour lines. You can write the function in explicit or parameterized notation. plotf_surfcontour 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_surfcontour 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.
