# NAME¶

**plmesh** - Plot surface mesh

# SYNOPSIS¶

**plmesh**(*x*, *y*, *z*, *nx*, *ny*,
*opt*)

# DESCRIPTION¶

Plots a surface mesh within the environment set up by
**plw3d**(3plplot). The surface is defined by the matrix
*z*[*nx*][*ny*] , the point *z*[i][j] being the value of
the function at (*x*[i], *y*[j]). Note that the points in vectors
*x* and *y* do not need to be equally spaced, but must be stored
in ascending order. The parameter *opt* controls the way in which the
surface is displayed. For further details see the PLplot documentation.

Redacted form: **plmesh(x, y, z, opt)**

This function is used in example 11.

# ARGUMENTS¶

*x*(**PLFLT_VECTOR**(3plplot), input)- A vector containing the x coordinates at which the function is evaluated.
*y*(**PLFLT_VECTOR**(3plplot), input)- A vector containing the y coordinates at which the function is evaluated.
*z*(**PLFLT_MATRIX**(3plplot), input)- A matrix containing function values to plot. Should have dimensions of
*nx*by*ny*. *nx*(**PLINT**(3plplot), input)- Number of
*x*values at which function has been evaluated. *ny*(**PLINT**(3plplot), input)- Number of
*y*values at which function has been evaluated. *opt*(**PLINT**(3plplot), input)- Determines the way in which the surface is represented:
*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.
