plmesh
(x, y, z, nx, ny, opt); |
Plots a surface mesh within the environment set up by plw3d. The
surface is defined by the two-dimensional array
z[nx][ny],
the point z[i][j] being the
value of the function at (x[i],
y[j]). Note that the points in
arrays x and
y do not need to be equally
spaced, but must be stored in ascending order. The parameter
opt controls the way in
which the surface is displayed. For further details see the Section called Three Dimensional Surface Plots in Chapter 3.
- x
(PLFLT *, input)
Pointer to set of x coordinate values at which the function is
evaluated.
- y
(PLFLT *, input)
Pointer to set of y coordinate values at which the function is
evaluated.
- z
(PLFLT **, input)
Pointer to a vectored two-dimensional array with set of
function values.
- nx
(PLINT, input)
Number of x values at
which function is evaluated.
- ny
(PLINT, input)
Number of y values at
which function is evaluated.
- opt
(PLINT, input)
Determines the way in which the surface is represented:
opt=1: Lines
are drawn showing
z as a function
of x for each
value of y[j].
opt=2: Lines
are drawn showing
z as a function
of y for each
value of x[i].
opt=3: Network
of lines is drawn connecting points at which function is
defined.
