plot3d: Plot 3-d surface plot for Fortran 77

plot3d (x, y, z, nx, ny, opt, side, mx);

When called from Fortran 77, this routine has the same effect as when invoked from C. The interpretation of all parameters (see plot3d) is also the same except there is an additional parameter given by:

mx (PLINT, input)

Length of array in x direction, for plotting subarrays.
