f01dgf performs one of the matrix-matrix operations
where
and
are real triangular matrices, and
is a real scalar.
f01dgf computes the matrix product
or
for two upper triangular or two lower triangular matrices. The storage method for matrices
and
must match (e.g.,
and
must both be upper triangular or lower triangular matrices). When the transpose of the input matrix
is used during computation, the solution matrix
is a general matrix. Otherwise, the solution matrix
is a triangular matrix with the storage method identified by the input argument
uplo.
