blas-vector-base

Vocabulary

math.blas.vectors

Class description

The base class for all BLAS vector types. Objects of this type should not be created directly; instead, instantiate one of the typed subclasses:

•	float-blas-vector
•	double-blas-vector
•	complex-float-blas-vector
•	complex-double-blas-vector

All of these subclasses share the same tuple layout:

•	underlying contains an alien pointer referencing or byte-array containing a packed array of float, double, float complex, or double complex values;
•	length indicates the length of the vector;
•	and inc indicates the distance, in elements, between elements.
