#### `plot3dcl`: Magnitude colored plot surface with contour for z[x][y] with y index limits

`plot3dcl (` | x,
| y,
| z,
| nx,
| ny,
| opt,
| clevel,
| nlevel,
| indexxmin,
| indexxmax,
| indexymin,
| indexymax`)`;

When the implementation is completed this variant of `plot3dc` (see that function's documentation for more details) should be suitable for the case where the area of the ``x``, ``y`` coordinate grid where ``z`` is defined can be non-rectangular. The implementation is incomplete so the last 4 parameters of plot3dcl; ``indexxmin``, ``indexxmax``, ``indexymin``, and ``indexymax``; are currently ignored and the functionality is otherwise identical to that of `plot3dc`.

`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 the function is evaluated.

`ny` (`PLINT`, input)

  Number of ``y`` values at which the function is evaluated.

`opt` (`PLINT`, input)

  Determines the way in which the surface is represented. To specify more than one option just add the options, e.g. DRAW_LINEXY + MAG_COLOR

  - ``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.

  - ``opt`=MAG_COLOR`: Each line in the mesh is colored according to the z value being plotted. The color is used from the current color map 1.

  - ``opt`=BASE_CONT`: A contour plot is drawn at the base XY plane using parameters `nlevel` and `clevel`.

  - ``opt`=DRAW_SIDES`: draws a curtain between the base XY plane and the borders of the plotted function.

`clevel` (`const PLFLT *`, input)

  Pointer to the array that defines the contour level spacing.

`nlevel` (`PLINT`, input)

  Number of elements in the `clevel` array.

`indexxmin` (`PLINT`, input)

  The index value (which must be ≥ 0) that corresponds to the first ``x`` index where ``z`` is defined.

`indexxmax` (`PLINT`, input)

  The index value (which must be ≤ ``nx``) which corresponds (by convention) to one more than the last ``x`` index value where ``z`` is defined.

`indexymin` (`const PLINT *`, input)

  Array of ``y`` index values which all must be ≥ 0. These values are the first ``y`` index where ``z`` is defined for a particular ``x`` index in the range from ``indexxmin`` to ``indexxmax - 1``. The dimension of ``indexymin`` is ``indexxmax``.

`indexymax` (`const PLINT *`, input)

  Array of ``y`` index values which all must be ≤ ``ny``. These values correspond (by convention) to one more than the last ``y`` index where ``z`` is defined for a particular ``x`` index in the range from ``indexxmin`` to ``indexxmax - 1``. The dimension of ``indexymax`` is ``indexxmax``.

Redacted form:

- General: `plot3dcl(x, y, z, opt, clevel, indexxmin, indexymin, indexymax)`

- Perl/PDL: Not available?

This function is not used in any example.
