                      If this function is called on a vector v on a distributed communicator only the +local part is written in output. To get a single MatrixMarket file with the whole +vector when appropriate, e.g. for debugging purposes, one could gather the whole +vector on a single rank and then write it. Consider the following example for a double +precision vector +

                      +

                      +

                      +real(psb_dpk_), allocatable :: vglobal(:)

+end if
+call deallocate(vglobal, stat=info)

                      To simplify this procedure in C, there is a utility function +
