Description
The
mkl_graph_vector_get_sparse
routine exports the sparse representation of a graph vector. All output arguments are optional and will not be used if NULL pointers are passed. For indices
and values
the type of the elements can be obtained from a corresponding parameter of type mkl_graph_type_t
.The routine .
mkl_graph_vector_get_sparse
does not change the ownership of the data. In particular, you should not directly deallocate the returned pointers. A call to mkl_graph_vector_destroy
will deallocate any data allocated by Intel® oneAPI Math Kernel Library
If only information about the number of rows or the number of columns is needed,
mkl_graph_vector_get_property
can be used instead of mkl_graph_vector_get_sparse
.Input Parameters
- v
- A graph vector from which data are retrieved.
Output Parameters
- dim
- Dimension of the vector. Ignored if NULL is passed.
- nnz
- Number of non-zero entries in the vector. Ignored if NULL is passed.
- indices
- A pointer to an array which contains zero-based indices for the non-zero entries in the vectorv. Type of the array elements can be deduced fromindices_type. Ignored if NULL.
- indices_type
- Type of the elements of theindicesarray. Refer to Graph API Glossary for a list of possible options. Ignored if NULL is passed.
- values
- A pointer to an array which contains values for the nonzero entries in the vectorv. The type of the array elements can be deduced fromvalues_type. Ignored if NULL.
- values_type
- Type of the elements of thevaluesarray. Refer to Graph API Glossary for a list of possible options. Ignored if NULL is passed.
Return Values
The function returns a value indicating whether the operation was successful or not and why. Refer to Graph API Glossary for a list of possible options.
Optimization Notice

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors.
