Get the value of some of the elements of this matrix. Parameters: row  start reading the elements of this matrix from row number "row". col  start reading the elements of this matrix from column number "col". A  Any array to hold the values from this matrix. ldA  the leading dimension of A. rowExtent  get rowExtent rows from this matrix. colExtent  get colExtent columns from this matrix. Implemented in DenseGenMatrix, DenseSymMatrix, SparseGenMatrix, and SparseSymMatrix.

virtual void DoubleMatrix::fromGetDiagonal (  int    idiag, OoqpVector &    x )  [pure virtual]

Get some of the diagonal elements of this matrix. Parameters: idiag  the index of the first diagonal element to be read. x  a vector to hold the diagonal elements The length of x is the number of diagonal elements to be gotten. Typically x will have length less than the length of the diagonal. Implemented in DenseGenMatrix, DenseSymMatrix, SparseGenMatrix, and SparseSymMatrix.

virtual void DoubleMatrix::fromGetSpRow (  int    row, int    col, double    A[], int    lenA, int    jcolA[], int &    nnz, int    colExtent, int &    info )  [pure virtual]

Get one sparse row from this matrix. Parameters: row  get row number "row" col  ignore all elements of the row before column "col" A  store the values of the sparse row in A lenA  the length of A jcolA  an array of length lenA containing the column index of each element in the sparse row colExtent  ignore all elements of the row that have column indices greater than or equal to col + colExtent info  info is 0 if and only if the sparse row can fit into A.
