Function Documentation

◆ TimeGLMGEEInitialize()

int TimeGLMGEEInitialize ( char *  class,
char *  type,
void *  s,
void *  m 
)

Initialize the GLM-GEE (_GLM_GEE_) time integation method: This function allocates the arrays to store the Butcher tableaux, and sets their coefficients, as well as other parameters for the GLM-GEE methods.

Reference:

Parameters
classClass of time integration method; must match _GLM_GEE_
typeName of the _GLM_GEE_ method to use
sObject of type GLMGEEParameters
mMPI object of type MPIVariables
