MESHGRID Cartesian rectangular grid in 2-D or 3-D
[X,Y] = MESHGRID(x,y) returns 2-D grid coordinates based on the
coordinates contained in vectors x and y. X is a matrix where each row
is a copy of x, and Y is a matrix where each column is a copy of y. The
grid represented by the coordinates X and Y has length(y) rows and
length(x) columns.
[X,Y,Z] = MESHGRID(x,y,z) returns 3-D grid coordinates defined by the
vectors x, y, and z. The grid represented by X, Y, and Z has size
length(y)-by-length(x)-by-length(z).
[X,Y] = MESHGRID(x) is the same as [X,Y] = MESHGRID(x,x), returning
square grid coordinates with grid size length(x)-by-length(x).
[X,Y,Z] = MESHGRID(x) is the same as [X,Y,Z] = MESHGRID(x,x,x),
returning 3-D grid coordinates with grid size
length(x)-by-length(x)-by-length(x).
MESHGRID outputs are typically used for the evaluation of functions of
two or three variables and for surface and volumetric plots.
MESHGRID and NDGRID are similar, but MESHGRID is restricted to 2-D and
3-D while NDGRID supports 1-D to N-D. In 2-D and 3-D the coordinates
returned by each function are the same. The difference is the shape of
their outputs. For grid vectors x, y, and z of length M, N, and P
respectively, NDGRID(x,y) outputs have size M-by-N while MESHGRID(x,y)
outputs have size N-by-M. Similarly, NDGRID(x,y,z) outputs have size
M-by-N-by-P while MESHGRID(x,y,z) outputs have size N-by-M-by-P.
Example: Evaluate and plot the two-variable function
f(x,y) = x*exp(-x^2-y^2) for -2 <= x <= 2 and -4 <= y <= 4
[X,Y] = meshgrid(-2:.2:2,-4:.4:4);
F = X .* exp(-X.^2 - Y.^2);
surf(X,Y,F)
Class support for inputs x, y, and z:
float: double, single
integer: uint8, int8, uint16, int16, uint32, int32, uint64, int64
