plmesh - Plot surface mesh
plmesh(x, y, z, nx, ny,
opt)
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.
- 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.
