Matrix multiplication

Multiplies two matrices, routing to an accelerated backend when available. Plain numeric vectors supplied as y are promoted to a column matrix and the result is dropped back to a vector.

Usage

matmul(x, y)

Arguments

x

A matrix or aMatrix object.

y

A matrix, aMatrix object, or numeric vector.

Value

A matrix (or numeric vector when y was a vector) of dimensions nrow(x) by ncol(y).

Examples

A <- adgeMatrix(matrix(1:6, 2, 3))
B <- adgeMatrix(matrix(1:6, 3, 2))
matmul(A, B)
#> An amatrix dense matrix [cpu|policy=auto|precision=strict]
#> 2 x 2 Matrix of class "adgeMatrix"
#>      [,1] [,2]
#> [1,]   22   49
#> [2,]   28   64
