MatDenseHIPPlaceArray#

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#

You can return to the original array with a call to MatDenseHIPResetArray(). The user is responsible for freeing this array; it will not be freed when the matrix is destroyed. The array must have been allocated with hipMalloc().
