Re: Help Plotting Symbolic Vector Fields with Substitutions

[WARDEVIL_UFO]

I went ahead and posted the code with your mods on the Octave Symbolic page.
Would you mind taking a look, and tell me what you think?  I also applied
the same style of mods to my spherical and cylindrical programs.  The style
of arguments you suggested for function_handle successfully plots correctly
on both my end and also on Octave online!  So those are some major hurdles
knocked out of the way!  

One little (potential) hiccup remains.  If a symbolic function had an actual
floating point valued coefficient or exponent, would using rat() for
heuristics be acceptable in that case, or is there some other preferred way? 
For instance, if  I modify  my iComponent to be sin(pi .*y ./2.01) that
triggers rats() warning.
