## Syntax

contour(z)

contour(z, n)

contour(z, h)

contour(x, y, z)

contour(x, y, z, n)

contour(x, y, z, h)

[c, obj] = contour(z)

[c, obj] = contour(z, n)

[c, obj] = contour(z, h)

[c, obj] = contour(x, y, z)

[c, obj] = contour(x, y, z, n)

[c, obj] = contour(x, y, z, h)

## Description

Generates a contour plot.

Examples

## Inputs

Name Description
x Specifies the surface from z in relation to the x-plane. x is a real vector or matrix. If x is a vector, the length of x must be equal to the number of columns of z. If x is a matrix, x and z must be of the same size.
y Specifies the surface from z in relation to the y-plane. y is a real vector or matrix. If y is a vector, the length of y must be equal to the number of rows of z. If y is a matrix, y and z must be of the same size.
z Specifies the height of the surface in relation to the z-plane. z is a matrix.
n Specifies the number of contour lines you want to plot.
h Specifies the height levels. h is a vector. length(h) must equal the number of contour lines you want to plot.

## Outputs

Name Description
c Returns the contour lines of the surface z. c is a real matrix with two rows. The first column of c indicates the height level, h, and the number of coordinates, k, of the contour line at that height level. The next k columns specify the x- and y-coordinates of the contour line.
obj Returns the reference to the contour line LabVIEW creates. obj is a reference to a line object.
