( | x, |

Plots a surface mesh within the environment set up by plw3d
. The
surface is defined by the two-dimensional array
,
the point z
[nx
][ny
]
being the
value of the function at z
[i][j](
. Note that the points in
arrays x
[i],
y
[j])
and
x
do not need to be equally
spaced, but must be stored in ascending order. The parameter
y
controls the way in
which the surface is displayed. For further details see the section called “Three Dimensional Surface Plots”.
opt
x
(const PLFLT *
, input)
Pointer to set of x coordinate values at which the function is evaluated.
y
(const PLFLT *
, input)
Pointer to set of y coordinate values at which the function is evaluated.
z
(const PLFLT * const *
, input)
Pointer to a vectored two-dimensional array with set of function values.
nx
(PLINT
, input)
Number of
values at
which function is evaluated.
x
ny
(PLINT
, input)
Number of
values at
which function is evaluated.
y
opt
(PLINT
, input)
Determines the way in which the surface is represented:
: Lines
are drawn showing
opt
=DRAW_LINEX
as a function
of z
for each
value of x
.
y
[j]
: Lines
are drawn showing
opt
=DRAW_LINEY
as a function
of z
for each
value of y
.
x
[i]
: Network
of lines is drawn connecting points at which function is
defined.
opt
=DRAW_LINEXY
Redacted form: plmesh(x, y, z, opt)
This function is used in example 11.
