BlasL3SyMM

Computes a matrix-matrix product where the input matrix A is symmetric.

C = alpha*A*B + beta*C  or

C = alpha*B*A + beta*C,

where A is a symmetric matrix of m-by-m size if side='L', or n-by-n size otherwise; B and C are m-by-n matrices.

BLAS function SYMM.

Computing for type matrix<double>

Computing for type matrix<float>

Parameters

side

[in]  Value from the ENUM_BLAS_SIDE enumeration, which specifies the side of the input matrix A in the product:

if side= 'L', then C = alpha*A*B + beta*C;

if side= 'R', then C = alpha*B*A + beta*C.

alpha

[in]  Scalar multiplier alpha.

B

[in]  Matrix B of size m-by-n.

beta

[in]  Scalar multiplier beta.

C

[in, out]  Result matrix C of size m-by-n. If beta is not zero, then matrix C should contain actual data before entry.If matrix size differs from m-by-n, then matrix C will be resized and zeroed.

Return Value

Return true if successful, otherwise false in case of an error.

Note

The input can be a symmetric, upper triangular or lower triangular matrix. Triangular matrices are assumed to be symmetric.

ENUM_BLAS_SIDE

An enumeration defining the side of the input matrix A in the product.
