The prototypes for the low-level CBLAS functions are declared in the file gsl_cblas.h. For the definition of the functions consult the documentation available from. This article shows how to use cblas (and others) in C with a simple example: To test the BLAS routines we want to perform a simple matrix-vector multiplication . Gentoo package sci-libs/cblas-reference: C wrapper interface to the F77 reference BLAS implementation in the Gentoo Packages Database.

Computes the dot product of two double-precision complex vectors. It seems like the extra parameter only adds complexity to already an already error-prone interface. DSPMV – symmetric packed matrix vector multiply.

ZDOTU – dot product. DGEMM – matrix matrix multiply. DTRMV – triangular matrix vector multiply. Hermitian rank 1 update: Calculates the dot product of the complex conjugate eeference a double-precision complex vector with a second double-precision complex vector. Overview The vecLib framework contains nine C header files not counting vec Lib.

In particular, I’m curious why there is an extra parameter for row vs. DSYRK – symmetric rank-k update to a matrix.

Double-Precision Complex Matrix Functions. Hermitian rank 2 update: Rank-k update—multiplies a symmetric matrix by its transpose and adds a second matrix double precision.

DGER – performs the referemce 1 operation A: STPMV – triangular packed matrix vector multiply. CSWAP – swap x and y. SSYR2 – performs the symmetric rank 2 operation, A: Scales a Hermitian band matrix, then multiplies by a vector, then adds a vector double-precision complex. Scales a general band matrix, then multiplies by a vector, then adds a vector single-precision complex.

The new build system was developed in collaboration with Kitware Inc. Instead, describe the problem and what has been done so reerence to solve it.

DSYR2 – performs the symmetric rank 2 operation, A: Scales a symmetric matrix, multiplies by a vector, then scales and adds another vector single precision. Please refer tools built under Windows vblas Cmake the cross-platform, open-source build system. SSBMV – symmetric banded matrix vector multiply. ZSYMM – symmetric matrix matrix multiply.

Returns the index of the element with the largest absolute value in a vector single-precision complex.
