Hi all,
I have two questions about memory management of sparse_matrix_t :
1. When I create a matrix handle using routine mkl_sparse_?_create_csr, the handle will copy all data to new memory blocks? Or it only save the pointers in handle? If it copy all data to new block, and the routine mkl_sparse_destroy will free these memory blocks or not ?
2. As the result of routine mkl_sparse_spmm , is it created in mkl routines？I will call destroy routine for it ? And then the internal data like column indexes array and matrix values array should be free expicit or not?
By the way, I found routines declared in header file : mkl_sparse_?_set_value, but they are not found in manual. And there are comment about these routines:
/* update existing value in the matrix ( for internal storage only, should not work with user-allocated matrices) */
It means I can not using them in my code?
Thanks,
