Calculates the butcher tableau for a given order.
Project description
Butcher Tableau
Calculates the Butcher Tableau for a given order.
Calculates A, B, and C for a given order and method.
This class calculates the transformation matrix, T, and its respective inverse. (However small errors may exist in the method used)
It can also calculate the interpolator coefficients, P, for a cubic polynomial spline.
butchertableau.py
Example
Code
import butchertableau as bt
order = 7
X = bt.butcher(order, 15)
A, B, C = X.radau()
Ainv = X.inv(A)
T, TI = X.Tmat(Ainv)
P = X.P(C)
print(P)
