NAME

6       plmesh - Plot surface mesh
7

SYNOPSIS

9       plmesh(x, y, z, nx, ny, opt)
10

DESCRIPTION

12       Plots  a  surface mesh within the environment set up by plw3d(3plplot).
13       The surface is defined by the matrix z[nx][ny] , the point z[i][j]  be‐
14       ing  the value of the function at (x[i], y[j]). Note that the points in
15       vectors x and y do not need to be equally spaced, but must be stored in
16       ascending  order.  The parameter opt controls the way in which the sur‐
17       face is displayed.  For further details see the PLplot documentation.

19       Redacted form: plmesh(x, y, z, opt)

ARGUMENTS

24       x (PLFLT_VECTOR(3plplot), input)
25              A vector containing the x coordinates at which the  function  is
26              evaluated.
27
28       y (PLFLT_VECTOR(3plplot), input)
29              A  vector  containing the y coordinates at which the function is
30              evaluated.
31
32       z (PLFLT_MATRIX(3plplot), input)
33              A matrix containing function values to plot.  Should have dimen‐
34              sions of nx by ny.
35
36       nx (PLINT(3plplot), input)
37              Number of x values at which function has been evaluated.
38
39       ny (PLINT(3plplot), input)
40              Number of y values at which function has been evaluated.
41
42       opt (PLINT(3plplot), input)
43              Determines   the  way  in  which  the  surface  is  represented:
44              opt=DRAW_LINEX : Lines are drawn showing z as a  function  of  x
45              for each value of y[j] .  opt=DRAW_LINEY : Lines are drawn show‐
46              ing  z  as  a  function  of  y  for  each  value   of   x[i]   .
47              opt=DRAW_LINEXY : Network of lines is drawn connecting points at
48              which function is defined.
