Convert a torch tensor (or R object) to a base R matrix

Converts a torch tensor to a base R matrix (moving it to the CPU first if needed); non-tensor input is coerced via as.matrix. Exposed so downstream packages (e.g. spiDE) doing their own GPU-blocked computation can convert results back to plain R without depending on torch internals.

Usage

toRMatrix(x)

Arguments

x

a torch tensor or an R object coercible via as.matrix.

Value

a base R matrix.

Examples

toRMatrix(matrix(1:4, 2, 2))
#>      [,1] [,2]
#> [1,]    1    3
#> [2,]    2    4
