## ncl_ezsrfc: Draws a perspective picture of a function of two

## NAME

EZSRFC - Draws a perspective picture of a function of two variables with hidden lines removed. The function is approximated by a two-dimensional array of heights. Use EZSRFC only if the entire array is to be drawn, the data points are equally spaced in the X-Y plane, there are no stereo pairs, and scaling is chosen internally.

## SYNOPSIS

CALL EZSRFC (Z,M,N,ANGH,ANGV,WORK)## C-BINDING SYNOPSIS

#include <ncarg/ncargC.h>
void c_ezsrfc (float *z, int m, int n, float angh, float angv,

float *work)

## DESCRIPTION

- Z
- The M by N array to be drawn.
- M
- The first dimension of Z.
- N
- The second dimension of Z.
- ANGH
- Angle in degrees in the X-Y plane to the line of sight (counterclockwise from the plus-X axis).
- ANGV
- Angle in degrees from the X-Y plane to the line of sight (positive angles are above the middle Z, negative below).
- WORK
- A scratch storage dimensioned at least 2*M*N+M+N.

## C-BINDING DESCRIPTION

The C-binding argument descriptions are the same as the FORTRAN argument descriptions, with the following exceptions:- z
- The n by m array to be drawn.
- m
- The second dimension of z.
- n
- The first dimension of z.

## EXAMPLES

Use the ncargex command to see the following relevant examples: fsrezsrf, tsrfac.## ACCESS

To use EZSRFC or c_ezsrfc, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.## COPYRIGHT
