MATLAB meshgrid functions

Description

Generate X and Y matrices for three-dimensional plots.

Usage

meshgrid(x, y, z, nargout=2)

Arguments

x, y, z	numeric vectors of values
nargout	numeric scalar that determines number of dimensions to return

Details

In the first example below, the domain specified by vectors x and y are transformed into two arrays which can be used to evaluate functions of two variables and three-dimensional surface plots. The rows of the output array x are copies of the vector x; columns of the output array y are copies of the vector y.

The second example below is syntactic sugar for specifying meshgrid(x, x).

The third example below produces three-dimensional arrays used to evaluate functions of three variables and three-dimensional volumetric plots.

Value

Returns list containing eiher two or three matrices depending on the value of nargout.

x, y, z

output matrices

Note

Limited to two- or three-dimensional Cartesian space.
