```       plot3d - Plot 3-d surface plot

```

#### SYNOPSIS

```       plot3d(x, y, z, nx, ny, opt, side)

```

#### DESCRIPTION

```       Plots  a  three  dimensional surface plot within the environment set up by plw3d(3plplot).
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 PLplot
documentation. The only difference between plmesh(3plplot)  and  plot3d(3plplot)  is  that
plmesh(3plplot) draws the bottom side of the surface, while plot3d(3plplot) only draws the
surface as viewed from the top.

Redacted form: plot3d(x, y, z, opt, side)

This function is used in examples 11,21.

```

#### ARGUMENTS

```       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 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=DRAW_LINEX:  Lines  are
drawn  showing  z as a function of x for each value of y[j].  opt=DRAW_LINEY: Lines
are drawn showing z as a function of y for each value  of  x[i].   opt=DRAW_LINEXY:
Network of lines is drawn connecting points at which function is defined.

side (PLBOOL, input)
Flag to indicate whether or not ``sides'' should be draw on the figure.  If side is
true sides are drawn, otherwise no sides are drawn.
