Function cusparseXcsr2coo 

Source 
pub unsafe extern "C" fn cusparseXcsr2coo(
    handle: cusparseHandle_t,
    csrSortedRowPtr: *const c_int,
    nnz: c_int,
    m: c_int,

Expand description

This function converts the array containing the compressed row pointers (corresponding to CSR format) into an array of uncompressed row indices (corresponding to COO format).

It can also be used to convert the array containing the compressed column indices (corresponding to CSC format) into an array of uncompressed column indices (corresponding to COO format).

  • The routine requires no extra storage.
  • The routine supports asynchronous execution.
  • The routine supports CUDA graph capture.
