contours (MathScript RT Module Function)
Owning Class: geometry
Requires: MathScript RT Module
Syntax
c = contours(z)
c = contours(z, n)
c = contours(z, h)
c = contours(x, y, z)
c = contours(x, y, z, n)
c = contours(x, y, z, h)
Legacy Name: contourc
Description
Calculates the contour lines of a surface. You can use the contour function or the contouris function to generate a contour plot.
Inputs
| Name | Description |
|---|---|
| x | Specifies the surface from z in relation to the x-plane. x is a matrix. size(x) must equal size(z). |
| y | Specifies the surface from z in relation to the y-plane. y is a matrix. size(y) must equal size(z). |
| 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. |
Examples
z = peakfcn2d(50);
c = contours(z);
