Member Function Documentation

unsigned int VSymMatrix::getNumRows

(

)

const

Get number of rows (= number of colums).

Returns:

Number of rows.

Definition at line 148 of file VMatrix.cpp.

References numRows.

unsigned int VSymMatrix::invert

(

)

Matrix inversion.

Invert symmetric N-by-N matrix V in symmetric storage mode V(1) = V11, V(2) = V12, V(3) = V22, V(4) = V13, . . . replaced by inverse matrix

Method of solution is by elimination selecting the pivot on the diagonal each stage. The rank of the matrix is returned in NRANK. For NRANK ne N, all remaining rows and cols of the resulting matrix V are set to zero.

Exceptions:

1	: matrix is singular.

Returns:

Rank of matrix.
