regoperator

Computes the discrete approximation to the derivative regularization operators.

Syntax

L = regoperator(r,order)

Parameters

• d - Derivative order (integer scalar)
• r - Distance axis (N-array)

Returns

• L - Regularization operator matrix ((N-d)xN-matrix)

Description

The function can be called as follows

L = regoperator(r,d)

Computes the discrete approximation L to the derivative operator of order d on an arbitrarily incremented distance vector r with N points. All finite difference matrix coefficients are computed via Fornberg’s method.
