## 42 Sparse BLAS Support

The Sparse Basic Linear Algebra Subprograms (BLAS) define a set of fundamental operations on vectors and sparse matrices which can be used to create optimized higher-level linear algebra functionality. GSL supports a limited number of BLAS operations for sparse matrices.

The header file `gsl_spblas.h` contains the prototypes for the sparse BLAS functions and related declarations.
