Member Function Documentation

virtual void GenMatrix::atPutDense (  int    row,
int    col,
double *    A,
int    lda,
int    rowExtent,
int    colExtent
)  [pure virtual]
 

Set the value of some of the elements of this matrix.

DoubleMatrix::fromGetDense

Implemented in DenseGenMatrix, and SparseGenMatrix.

virtual void GenMatrix::atPutSpRow (  int    col,
double    A[],
int    lenA,
int    jcolA[],
int &    info
)  [pure virtual]
 

Put a sparse row into this matrix.

The meaning of the parmameters is the same as in fromGetSpRow.

DoubleMatrix::fromGetSpRow

Implemented in DenseGenMatrix, and SparseGenMatrix.

virtual void GenMatrix::atPutSubmatrix (  int    destRow,
int    destCol,
DoubleMatrix &    M,
int    srcRow,
int    srcCol,
int    rowExtent,
int    colExtent
)  [pure virtual]
 

Put a submatrix of M into this matrix.

Parameters:
destRow  The top row of the submatrix of M is placed at destRow.
destCol  The leftmost column of the submatrix of M is placed at destCol.
srcRow  The first row of the submatrix of M is srcRow.
srcCol  The first column of the submatrix of M is srcCol.
rowExtent  rowExtent rows are copied from M.
colExtent  colExtent columns are copied from M.

Implemented in DenseGenMatrix, and SparseGenMatrix.

virtual void GenMatrix::randomize (  double    alpha,
double    beta,
double *    seed
)  [pure virtual]
 

Fill this matrix with random elements.

Parameters:
alpha  the elements will be no smaller than alpha.
beta  the elements will be no larger than beta.
seed  a arbitrary number used to seed the random number generator.

Implemented in DenseGenMatrix, and SparseGenMatrix.
