Changes to nzMatrix

Simplified Matrix Multiplication

The matrix multiplication procedure (GEMM) has been simplified. Previously, users chose

whether to use GEMM or GEMM_LARGE, based on speed requirements and matrix size.

(GEMM was faster but could not calculate larger matrices.) With this release, the GEMM

procedure has been enhanced and GEMM_LARGE is no longer required. Beginning

with this release, GEMM uses the following signatures (the second being previously part of

GEMM_LARGE):

 GEMM (nvarchar(any), nvarchar(any), nvarchar(any))

 GEMM (nvarchar(any), BOOLEAN, nvarchar(any), BOOLEAN, nvarchar(any)))

The system selects the appropriate algorithm, transparent to the user, based on the size of

the processed matrices and architecture of the hardware. Note that, for backward compati-

bility, the system continues to recognize the GEMM_LARGE stored procedure.
