MatDenseCUDAGetArrayWrite#
Provides write access to the CUDA buffer inside a MATDENSECUDA matrix.
Synopsis#
Not Collective
Input Parameter#
A - the matrix
Output Parameter#
a - the GPU array in column major order
Notes#
The data on the GPU may not be updated due to operations done on the CPU. If you need updated
data, use MatDenseCUDAGetArray().
The array must be restored with MatDenseCUDARestoreArrayWrite() when no longer needed.
