Sparse matrix by dense matrix multiplication

Sparse matrix by dense matrix multiplication

Usage

sparse_matmul_dense(x, y)

Arguments

x

A cudasparse matrix.

y

A numeric matrix or cudatensor.

Value

A dense cudatensor. The native backend keeps the result on CUDA; compatibility backends retain their existing portable CPU result.

Examples

x <- cuda_sparse(diag(3), device = "cpu")
sparse_matmul_dense(x, matrix(1:6, 3, 2))
#> <cudatensor[3x2] device=cpu backend=base dtype=float64>
#>      [,1] [,2]
#> [1,]    1    4
#> [2,]    2    5
#> [3,]    3    6
