**plmeshc** - Magnitude colored plot surface mesh with contour.

**plmeshc**(*x*, *y*, *z*, *nx*, *ny*, *opt*, *clevel*, *nlevel*)

Identical to **plmesh** but with extra functionalities: the surface mesh can be colored accordingly to the current z value being plotted, a contour plot can be drawn at the base XY plane, and a curtain can be drawn between the plotted function border and the base XY plane.

Redacted form: **plmeshc(x, y, z, opt, clevel)**

This function is used in example 11.

*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. 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 colormap 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* (PLFLT *, input)

Pointer to the array that defines the contour level spacing.

*nlevel* (PLINT, input)

Number of elements in the clevel array.
