MatDenseCUDARestoreArrayRead#

Restore read-only access to the CUDA buffer inside a MATDENSECUDA matrix previously obtained with a call to MatDenseCUDAGetArrayRead().

Synopsis#

Not Collective

Input Parameters#

  • A - the matrix

  • a - the GPU array in column major order

Note#

Data can be copied to the GPU due to operations done on the CPU. If you need write only access, use MatDenseCUDAGetArrayWrite().
