Constructor Detail

MatrixBLAS3

public MatrixBLAS3()

Create a matrix BLAS with the default BLAS implementation and a base index of '0'. All computations will use elements A[0...(nrow-1)][0...(ncol-1)].

MatrixBLAS3

public MatrixBLAS3(int base)

Create a matrix BLAS with a default BLAS implementation and an explicit base index. Typically 'base' will be '0' or '1'. All computations will use elements A[base...(nrow-1)][base...(ncol-1)].

MatrixBLAS3

public MatrixBLAS3(int base,
                   BLAS3I blas3)

Create a matrix BLAS with an explicit BLAS implementation and an explicit base index. Typically 'base' will be '0' or '1'. All computations will use elements A[base...(nrow-1)][base...(ncol-1)].

dgemm

public void dgemm(boolean transposeA,
                  boolean transposeB,
                  double alpha,
                  ContiguousMatrixI A,
                  ContiguousMatrixI B,
                  double beta,
                  ContiguousMatrixI C)
           throws BlasException

Computes: C = alpha*A*B + beta*C.

zgemm

public void zgemm(boolean transposeA,
                  boolean transposeB,
                  ComplexI alpha,
                  ContiguousMatrixI A,
                  ContiguousMatrixI B,
                  ComplexI beta,
                  ContiguousMatrixI C)
           throws BlasException

Computes: C = alpha*A*B + beta*C.
