// Constructor

// Public Methods

Causes the condenser to form \(A_{ee}^* = A_{ee} -A_{ei} A_{ii}^{-1} A_{ie}\), where \(A_{ii}\) is the first numInt rows of the \(A\) matrix. The original \(A\) is changed as a result. \(A_{ee}^*\) is to be stored in \(A_{ee}\).

int condenseRHS(int numInt);

Causes the condenser to form \(B_e^* = B_e - A_{ei} A_{ii}^{-1} B_i\), where \(A_{ii}\) is the first numInt rows of \(A\). The original \(B\) is changed as a result. \(B_e^*\) is to be stored in \(B_e\).

int computeCondensedMatVect(Vector &u, int numInt);

Causes the condenser to form \(A_{ee} u\).

Matrix &getCondensedA(void);

Returns the contents of \(A_{ee}\) as a matrix.

Vector &getCondensedRHS(void);

Returns the contents of \(B_e\) as a Vector.

Vector &getCondensedMatVect(void);

Returns the contents of the last call to computeCondensedMatVect().

int setComputedXext(const Vector &u);

Sets the computed value of the unknowns in \(X_e\) corresponding to the external equations to u. The number of external equations is given by the size of vector \(u\).

int solveXint(void);

To compute the internal equation numbers \(X_i\) given the value set for the external equations in the last call to setComputedXext().
