Description

gemm

half, float, double, std::complex<float>, std::complex<double>, mixed

Computes a matrix-matrix product with general matrices.

hemm

std::complex<float>, std::complex<double>

Computes a matrix-matrix product where one input matrix is Hermitian and one is general.

herk

std::complex<float>, std::complex<double>

Performs a Hermitian rank-k update.

her2k

std::complex<float>, std::complex<double>

Performs a Hermitian rank-2k update.

symm

float, double, std::complex<float>, std::complex<double>

Computes a matrix-matrix product where one input matrix is symmetric and one matrix is general.

syrk

float, double, std::complex<float>, std::complex<double>

Performs a symmetric rank-k update.

syr2k

float, double, std::complex<float>, std::complex<double>

trmm

float, double, std::complex<float>, std::complex<double>

Computes a matrix-matrix product where one input matrix is triangular and one input matrix is general.

trsm

float, double, std::complex<float>, std::complex<double>

Solves a triangular matrix equation (forward or backward solve).

Optimization Notice

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.

Notice revision #20110804

This notice covers the following instruction sets: SSE2, SSE4.2, AVX2, AVX-512.
