# Level 2 CBLAS

This is an interface to “BLAS Level 2 Routines”, which perform basic matrix-vector operations. Each C routine in this group has an additional parameter of type CBLAS_ORDER (the first argument) that determines whether the two-dimensional arrays use column-major or row-major storage.
