I had spent some time implementing rational chebychev approximation as part of a course. The code is at [1]. It is mostly a port of the NR code. The problems that will arise is how to determine the number of coefficients that is to be calculated to achieve a certain accuracy. This will change with the function and if we try to overfit the approximation, then the accuracy is not that great.
Thanks, Bharath M R [1] https://github.com/catchmrbharath/compmeth/blob/master/week4/rational.py PS: The code is really bad. I had just started out with python then. -- You received this message because you are subscribed to the Google Groups "sympy" group.
