Package blas provides interfaces for the BLAS linear algebra standard.
|
|
|
|
All methods must perform appropriate parameter checking and panic if
|
|
provided parameters that do not conform to the requirements specified
|
|
by the BLAS standard.
|
|
|
|
Quick Reference Guide to the BLAS from http://www.netlib.org/lapack/lug/node145.html
|
|
|
|
This version is modified to remove the "order" option. All matrix operations are
|
|
on row-order matrices.

Matrix types
|
|
|
|
GE - GEneral GB - General Band
|
|
SY - SYmmetric SB - Symmetric Band SP - Symmetric Packed
|
|
HE - HErmitian HB - Hermitian Band HP - Hermitian Packed
|
|
TR - TRiangular TB - Triangular Band TP - Triangular Packed
|
|
|
|
Options
|
|
|
|
trans = NoTrans, Trans, ConjTrans
|
|
uplo = Upper, Lower
|
|
diag = Nonunit, Unit
|
|
side = Left, Right (A or op(A) on the left, or A or op(A) on the right)
|
|
|
|
For real matrices, Trans and ConjTrans have the same meaning.
|
|
For Hermitian matrices, trans = Trans is not allowed.
|
|
For complex symmetric matrices, trans = ConjTrans is not allowed.
