Pade Approximation (Not in Base Package)

Determines the coefficients of a rational polynomial to best suit a given set of first derivatives. Details

m is the degree of the polynomial of the numerator.
n is the degree of the polynomial of the denominator.
C[0..m+n] is the array describing the first derivatives of the given function.
A[0..m] is the polynomial of the numerator.
B[0..n] is the polynomial of the denominator.
error returns any error or warning condition from the VI.

Pade Approximation Details

Let f be a given function with known values

There is a unique rational polynomial

with

The rational polynomial can be determined by solving a special linear equation.
