A new matrix storage is proposed for Computational Fluid Dynamics in Finite Elements.The main idea is to store assembled matrices in an Element By Element (EBE) way.This storage optimizes the memory required and speeds up the classical EBE matrix-vector product, but also enables to perform a ...
SGEMV and DGEMV compute the matrix-vector product for either a real general matrix or its transpose, using the scalars α and β, vectors x and y, and matrix A or its transpose: y← β y+α Ax y ← βy+α ATx CGEMV and ZG...
In the present algorithm, contributions to the matrix-vector product are obtained either with transformed integrals stored on disk or by recomputation of integrals over atomic basis functions. Formation of the Ĥ2ph−2hY2ph product is the most difficult phase of~the matrix-vector multiplication....

Using an efficient way to compute the product of a Toeplitz matrix and a vector, a sub-quadratic arithmetic complexity scheme for field multiplication over binary extension fields has recently been proposed by Fan and Hasan. The scheme has been developed using a shifted polynomial basis for the ...
Furthermore, as we'll show in Section 4, this invariance extends to the cost of a sparse matrix-vector product using the coordinate format. Since the best-case SpMV performance of ELL exceeds that of COO, a hybrid ELL/COO format, which stores the majority of matrix entries in ELL and ...
I have need to implement the vector-matrix product (not matrix-vector product).which function can I use?I have tried with dgemv (with the parameter trans = 112) but it doesn't work. I have the following matrix and vectors: x = -1.2 -0.8 1.0 0 0.4 0.6 M = -0.4 0 0.4 -0.6 0 ...
