ezmeshc
(Not recommended) Combined mesh and contour plotter
ezmeshc
is not recommended. Use fmesh
instead.
Syntax
Description
ezmeshc(
creates a graph of
f(x,y), where
f is a symbolic expression that represents a mathematical function of
two variables, such as x and y.f
)
The function f is plotted over the default domain –2π < x < 2π, –2π < y < 2π. MATLAB® software chooses the computational grid according to the amount of variation that occurs; if the function f is not defined (singular) for points on the grid, then these points are not plotted.
ezmeshc(
plots f over the specified f
,domain
)domain
.
domain
can be either a 4-by-1 vector [xmin, xmax, ymin,
ymax] or a 2-by-1 vector [min, max] (where,
min < x < max,
min < y < max).
If f is a function of the variables u and
v (rather than x and y), then the
domain endpoints umin, umax, vmin,
and vmax are sorted alphabetically. Thus, ezmeshc(u^2 -
v^3,[0,1],[3,6])
plots u2 – v3 over 0 < u < 1, 3 < v <
6.
ezmeshc(___,
plots f over the default domain using an
n
)n
-by-n
grid. The default value for
n
is 60.
ezmeshc(___,'circ')
plots
f over a disk centered on the domain.
Examples
3-D Mesh Plot with Contours
Create a mesh/contour graph of the expression,
over the domain –5 < x < 5, –2π < y < 2π. Use the mouse to rotate the axes to better observe the contour lines (this picture uses a view of azimuth = –65 and elevation = 26).
