plotsh3d: Plot shaded 3-d surface plot

plotsh3d (x, y, z, nx, ny, side);

Plots a three dimensional shaded surface plot 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. 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.

side (PLINT, input)

Flag to indicate whether or not ``sides'' should be draw on the figure. If side=0 no sides are drawn, otherwise the sides are drawn.
