Wraps real and complex scalar routines in BLAS/LAPACK as traits for use in scalar-generic mathematical/scientific Rust crates.
Currently implements a small subset of BLAS and LAPACK routines, but more are being added over time. Contributions for any missing routines are welcome.
Access BLAS and LAPACK methods through the BlasScalar and LapackScalar traits, respectively. Enabling simba provides access to the LComplexField trait, a convenient unifying trait for the (f32, f64, c32, c64) types that also derives from simba::scalar::ComplexField.
Almost all simple routines with uniform patterns over all types
behave as defined in BLAS/LAPACK.
For a routine xgemm, where x is one
of the types s, d, c, or z, the trait name is written as Tgemm,
and the method is gemm.
For some routines that mix real and complex scalars, such as
yasum, where y = s, d, sc, dz, the traits are name RTasum,
while the methods are simply asum.
Routines with integer types such as ixamax correspond to
ITamax and amax.
Additional naming and behavioral complexities arise when
real and complex matrices are mixed together.
These are explicitly documented and wrapped over all
data types as uniformly as possible. In general, he
means "hermitian" for complex types and "symmetric" for real types,
while sy means "symmetric" for all types.
Likewise, un means unitary for complex types
and orthogonal for real types.
Related routines may be grouped under a single trait.
