MATLAB meshgrid functions
Generate X and Y matrices for three-dimensional plots.
meshgrid(x, y, z, nargout=2)
x, y, z |
numeric vectors of values |
nargout |
numeric scalar that determines number of dimensions to return |
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.
Returns list containing eiher two or three matrices depending on the
value of nargout.
x, y, z |
output matrices |
Limited to two- or three-dimensional Cartesian space.
