MatDenseHIPReplaceArray#

Allows one to replace the GPU array in a MATDENSEHIP matrix with an array provided by the user. This is useful to avoid copying an array into a matrix.

Synopsis#

Not Collective

Input Parameters#

  • mat - the matrix

  • array - the array in column major order

Note#

This permanently replaces the GPU array and frees the memory associated with the old GPU array. The memory passed in CANNOT be freed by the user. It will be freed when the matrix is destroyed. The array should respect the matrix leading dimension.
