Call: PLOT_SURFACE

matrix

The Matrix to be plotted.

This matrix should be 2-dimensional, and have a length of at least 2 in both directions. In the descriptions, the first index of the matrix will be written x, the second y.

The overall size of the matrix is limited to an amount that depends on the graphics system used (NAG or HIGZ) but is in both cases very large (around 10000 words at least).

The ordinates of the matrix have to be equidistant because of limitations in the underlying graphics packages.

\θ

Polar viewing angle, in degrees.

This argument is of type Number.

Default: 60\°.

\φ

Azimuthal viewing angle, in degrees.

This argument is of type Number.

Default: 60\°.

x-vector

A 1-dimensional Matrix with the x-coordinates of the matrix that is to be plotted.

Only the first and last element are used to set the scale along the x-axis of the plot. Hence, a function value matrix with non-equidistant ordinates will not be rendered correctly.

Whether a scale is actually plotted along the axes depends on the graphics system that is used.

If omitted, a range of [0, 1] is assumed.

y-vector

A 1-dimensional Matrix with the y-coordinates of the matrix that is to be plotted.

Only the first and last element are used to set the scale along the y-axis of the plot. Hence, a function value matrix with non-equidistant ordinates will not be rendered correctly.

Whether a scale is actually plotted along the axes depends on the graphics system that is used.

If omitted, a range of [0, 1] is assumed.

x-label

A String to be placed along the x-axis.

Whether a label is actually plotted along the axes depends on the graphics system that is used.

The label is shown using the LABELS text representation.

If omitted, the name of the global variable associated with x-vector is used, if there is one, otherwise the string 'x-axis' is taken.

y-label

A String to be placed along the y-axis.

Whether a label is actually plotted along the axes depends on the graphics system that is used.

The label is shown using the LABELS text representation.

If omitted, the name of the global variable associated with y-vector is used, if there is one, otherwise the string 'y-axis' is taken.

title

A String to be placed above the plot.

The title is shown using the TITLE text representation.

If omitted, the name of the global variable associated with matrix is used, if there is one, otherwise the title is left blank.
