GLMOrder

GLMOrder[glm]

computes the order of accuracy of glm.

Details and Options

  • The order of a general linear method is a integer greater than or equal to .
  • GLMOrder checks order conditions which assume high stage order, i.e., .

Basic Examples  (2)

Get the order of a DIMSIM:

A generic general linear method fails to satisfy any order condition:

Possible Issues  (2)

GLMOrder may underestimate the order for methods with low stage order:

Methods with floating point or rational approximations to coefficients may fail to satisfy order conditions by small, but nonzero residuals:
