Reshape a tensor without changing its values

Reshape a tensor without changing its values

Usage

tensor_reshape(x, shape)

Arguments

x

A cudatensor.

shape

Positive whole-number dimensions whose product equals length(x).

Value

A cudatensor on the same device with the requested shape.

Details

The native CUDA backend creates an allocation-free metadata view that shares the source device allocation. The source and reshaped tensor have independent external-pointer lifetimes, and the allocation is freed only after the final view is released. Compatibility backends retain their established reshape behavior.

Examples

x <- cuda_tensor(1:6, device = "cpu")
tensor_reshape(x, c(2, 3))
#> <cudatensor[2x3] device=cpu backend=base dtype=integer>
#>      [,1] [,2] [,3]
#> [1,]    1    3    5
#> [2,]    2    4    6
