[pstricks] cubic b-spline package?

[Michael Sharpe]

It turns out that the construction I asked about a few days ago may be  
carried out without much pain, and no Postscript programming. I placed  
a brief discussion of the problem, with an example illustration, at http://math.ucsd.edu/~msharpe/bsplinePstricks.pdf 
. The pstricks code carrying out the algorithm, and generating the  
picture, is at http://math.ucsd.edu/~msharpe/multipnode.tex
