ezsurf
(Not recommended) Plot 3-D surface
ezsurf
is not recommended. Use fsurf
instead.
Syntax
Description
ezsurf(
plots a two-variable
symbolic expression or function f
)f
(x,y)
over the range -2*pi < x < 2*pi
, -2*pi < y
< 2*pi
.
ezsurf(
plots
f
,[xmin,xmax])f
(x,y)
over the specified range
xmin < x < xmax
. This is the range along the
abscissa (horizontal axis).
ezsurf(
plots f
,[xmin,xmax,ymin,ymax])f
(x,y)
over the specified ranges
along the abscissa, xmin < x < xmax
, and the ordinate,
ymin < y < ymax
.
When determining the range values, ezsurf
sorts variables
alphabetically. For example, ezsurf(x^2 - a^3, [0,1,3,6])
plots x^2 - a^3
over
0 < a < 1
,
3 < x < 6
.
ezsurf(
plots the parametric
surface x,y,z
)x = x(s,t)
, y = y(s,t)
, z
= z(s,t)
over the range -2*pi < s < 2*pi
,
-2*pi < t < 2*pi
.
ezsurf(
plots the
parametric surface x,y,z
,[smin,smax])x = x(s,t)
, y = y(s,t)
,
z = z(s,t)
over the specified range smin < s
< smax
.
ezsurf(___,
specifies
the grid. You can specify n
)n
after the input arguments in
any of the previous syntaxes. By default, n = 60
.
ezsurf(___,'circ')
creates the surface plot
over a disk centered on the range. You can specify'circ'
after the input arguments in any of the previous syntaxes.

Tips
ezsurf
chooses the computational grid according to the amount of variation that occurs. Iff
is singular for some points on the grid, thenezsurf
omits these points. The value at these points is set toNaN
.
