Purpose
=======

ZCREATE_DIST_MATRIX reads the global matrix from three input arrays
and distribute it to the processes in a distributed compressed row format.

Arguments   
=========      

A             (output) SuperMatrix*
              Local matrix A in NR_loc format. 

M             (input) int_t
              The row number of the global matrix. 

N             (input) int_t
              The col number of the global matrix. 

NNZ           (input) int_t
              The number nonzeros in the global matrix. 

NZVAL_G       (input) doublecomplex*
              Nonzero values of the global matrix. 

ROWIND_G      (input) int_t*
              Row indices of the global matrix. 

COLPTR_G      (input) int_t*
              Columns pointers of the global matrix. 

GRID          (input) gridinof_t*
              The 2D process mesh.
