Interface SolveMatrixModifier

All Known Implementing Classes:

StiffnessMatrixScaler

public interface SolveMatrixModifier

Class that modifiers a solve or stiffness matrix and associated force vector. This can be used to convert ArtiSynth stiffness matrices to alternate forms that may be more suitable for different kinds of analysis.

Method Summary

Modifier and Type	Method and Description
void	modify(SparseBlockMatrix K, VectorNd f, java.util.ArrayList<DynamicComponent> comps) Modifies in place a solve or stiffness matrix K, along with an (optional) force vector f and component list comps.

Method Detail

modify

void modify(SparseBlockMatrix K,
            VectorNd f,
            java.util.ArrayList<DynamicComponent> comps)

Modifies in place a solve or stiffness matrix K, along with an (optional) force vector f and component list comps. If provided, comps lists the components associated with each block entry in K, and will be modified if any rows/columns in K are permuted or deleted. If provided, f and comps should have sizes equal to the row (or column) size of K.

Parameters:

K - stiffness matrix to transform

f - if non-null, force vector to transform

comps - if non-null, components associated with each block entry in K.
