Hi everyone, I want to do some polynomial fitting. Basically, the program should impose conditions on a polynomial function and its derivative, on a symbolic interval. The result is a linear algebraic system for the polynomial coefficients a0, a1, ... an. The key problem that I'm facing is how to obtain the sorted list of polynomial terms that is required as a row of the linear system matrix (type Matrix) for the solve_linear_system function.
I have posted this question already on Stack Overflow <http://stackoverflow.com/questions/26160213/how-to-convert-a-sympy-polynomial-into-a-list> but it seems that this mailing list is more active - I didn't get any feedback there. I have found the way to prevent commutation of variables <http://stackoverflow.com/a/16245991/735756>, but the problem is that I need the commutation to work to solve the linear system I get in the end. What is the best way to approach this problem? Thanks, Tomislav -- You received this message because you are subscribed to the Google Groups "sympy" group.
