Test the deviation of a given matrix from a Hermitian (or Unitary) matrix.

  • handle (intptr_t) – the handle to cuStateVec library.

  • matrix_type (MatrixType) – matrix type.

  • matrix (intptr_t) – host or device pointer to a matrix.

  • matrix_data_type (int) – data type of matrix.

  • layout (MatrixLayout) – enumerator specifying the memory layout of matrix.

  • n_targets (uint32_t) – the number of target bits, up to 15.

  • adjoint (int32_t) – flag to control whether the adjoint of matrix is tested.

  • compute_type (ComputeType) – compute type.

  • extra_workspace (intptr_t) – extra workspace.

  • extra_workspace_size_in_bytes (size_t) – extra workspace size.


host pointer, to store the deviation from certain matrix type.
