Zero Matrix CSR Format

Hi,

in order to implement a generic algorithm, I need to define the zero matrix in CSR format. Is it possible?

I have defined it with null arrays for elements, rows, etc.... but when I try to call the function mkl_sparse_d_add it crashes with  SPARSE_STATUS_NOT_INITIALIZED error.

How can I define the zero matrix in csr format?

Thanks in advance,

Joaquin
