I am fighting with memory leaks in some sparse matrix code. It looks I have some memory leak which is linked to the creation (or non destruction) of a matrix handle. I have some very simple questions. I could not find an answer in the documentation, so I am asking here. Here is the question.
I am constructing a sparse matrix using:
sparse_matrix_t A;
sparse_status_t ok=mkl_sparse_z_create_csr (&A,SPARSE_INDEX_BASE_ONE,nRows,nCols,ia,ia+1,ja,z);
The handle A is generated for the complex array z and the integer arrays ia and ja. I am trying to understand if the data in the arrays is copied in some new arrays or if the handle A refers to the original arrays. If I remember correctly. A refers to the original arrays but I would like to check. My current code keeps the arrays and does not delete them.
I am also trying to understand what happens when I destroy the matrix using the function mkl_sparse_destroy. Assuming arrays ia,ja and z are referred to by the handle, are these arrays deleted when I use mkl_sparse_destroy or do I need to delete them? As you can understand, I am trying to remove memory leaks.
Thanks for helping.
