contractSystem

public static LinearEqSystem contractSystem(LinearEqSystem system,
                                            java.util.List<java.lang.Integer> toRemove)

Provided with a model, this method gives matrix and vectors related to regression of a smaller model, whose links are a subset of original model's links. The matrix and vector get deep copied.

Parameters:

system - system of linear regression equations for a polynomial network

toRemove - list of rows/clos we want to exclude from the original model. Suggested use: with removeCR2Array or removeCR2List

Returns:

contracted system of linear equations. does not return the vector of unknowns
