Matrix multiplication for adgCMatrix

Dispatches %*% through the amatrix backend for sparse adgCMatrix objects on the left-hand side, preserving GPU residency metadata across the operation.

Usage

# S4 method for class 'adgCMatrix,ANY'
x %*% y

# S4 method for class 'adgCMatrix,matrix'
x %*% y

# S4 method for class 'adgCMatrix,Matrix'
x %*% y

# S4 method for class 'adgCMatrix,dgeMatrix'
x %*% y

# S4 method for class 'adgCMatrix,dgCMatrix'
x %*% y

# S4 method for class 'adgCMatrix,adgeMatrix'
x %*% y

# S4 method for class 'adgCMatrix,adgCMatrix'
x %*% y

Arguments

x

An adgCMatrix.

y

A matrix-like object: matrix, Matrix, adgeMatrix, adgCMatrix, or ANY.

Value

An adgeMatrix or adgCMatrix containing the product, with backend metadata inherited from x.

Examples

sp <- as(matrix(c(1, 0, 0, 2), 2, 2), "dgCMatrix")
A  <- adgCMatrix(sp)
B  <- matrix(1:4, 2, 2)
A %*% B
#> An amatrix dense matrix [cpu|policy=auto|precision=strict]
#> 2 x 2 Matrix of class "adgeMatrix"
#>      [,1] [,2]
#> [1,]    1    3
#> [2,]    4    8
