cuquantum.custatevec.apply_matrix_get_workspace_size¶

cuquantum.custatevec.apply_matrix_get_workspace_size(intptr_t handle, int sv_data_type, uint32_t n_index_bits, intptr_t matrix, int matrix_data_type, int layout, int32_t adjoint, uint32_t n_targets, uint32_t n_controls, int compute_type) → size_t[source]¶

This function gets the required workspace size for apply_matrix().

Parameters

handle (intptr_t) – the handle to the cuStateVec context.
sv_data_type (int) – Data type of the state vector.
n_index_bits (uint32_t) – the number of index bits of the state vector.
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.
adjoint (int32_t) – apply adjoint of matrix.
n_targets (uint32_t) – the number of target bits.
n_controls (uint32_t) – the number of control bits.
compute_type (ComputeType) – compute_type of matrix multiplication.

Returns

workspace size.
