Low-level BLAS functions (scipy.linalg.blas
)¶
This module contains low-level functions from the BLAS library.
New in version 0.12.0.
Note
The common overwrite_<>
option in many routines, allows the
input arrays to be overwritten to avoid extra memory allocation.
However this requires the array to satisfy two conditions
which are memory order and the data type to match exactly the
order and the type expected by the routine.
As an example, if you pass a double precision float array to any
S....
routine which expects single precision arguments, f2py
will create an intermediate array to match the argument types and
overwriting will be performed on that intermediate array.
Similarly, if a C-contiguous array is passed, f2py will pass a FORTRAN-contiguous array internally. Please make sure that these details are satisfied. More information can be found in the f2py documentation.
Warning
These functions do little to no error checking.
It is possible to cause crashes by mis-using them,
so prefer using the higher-level routines in scipy.linalg
.
