glas_dgemm

Performs general matrix-matrix multiplication.

Parameters

alpha double: scalar
asl Slice!(SliceKind.universal, [2], const(double)*): m ⨉ k matrix
bsl Slice!(SliceKind.universal, [2], const(double)*): k ⨉ n matrix
beta double: scalar. When beta is supplied as zero then the matrix csl need not be set on input.
csl Slice!(SliceKind.universal, [2], double*): m ⨉ n matrix with one stride equal to ±1.
settings ulong: Operation settings. Allowed flags are ConjA and ConjB.
Unified alias
