Suppose in Fortran, we have an array
u (0 : nxblock+1, 0 : nyblock+1)
where we want to send rows and columns of elements from 1 : nxblock and 1 : nyblock
in Fortran, arrays are stored column major order (C is row major)
Contiguous elements
MPI_Type_vector( nyblock, 1, nxblock+2, MPI_REAL, rowtype )
defines a row of elements 1:nyblock
0 nyblock+1
nxblock+1
