scipy.linalg.get_lapack_funcs¶
- scipy.linalg.get_lapack_funcs(names, arrays=(), dtype=None)[source]¶
Return available LAPACK function objects from names.
Arrays are used to determine the optimal prefix of LAPACK routines.
Parameters : names : str or sequence of str
Name(s) of LAPACK functions withouth type prefix.
arrays : sequency of ndarrays, optional
Arrays can be given to determine optiomal prefix of LAPACK routines. If not given, double-precision routines will be used, otherwise the most generic type in arrays will be used.
dtype : str or dtype, optional
Data-type specifier. Not used if arrays is non-empty.
Returns : funcs : list
List containing the found function(s).
Notes
This routines automatically chooses between Fortran/C interfaces. Fortran code is used whenever possible for arrays with column major order. In all other cases, C code is preferred.
In LAPACK, the naming convention is that all functions start with a type prefix, which depends on the type of the principal matrix. These can be one of {‘s’, ‘d’, ‘c’, ‘z’} for the numpy types {float32, float64, complex64, complex128} respectevely, and are stored in attribute typecode of the returned functions.
