Hi all, I am trying to get all the rows of a parallel matrix as individual vectors. For instance, if I have 72*4 matrix, I want to get 72 different vectors having size 4.
As far as I understood, MatGetRow is only for local rows, so MatGetOwnershipRange is used, however, when I tried this one, I couldn't get the whole and desired row vectors. In MatGetRow explanation, it is written that I should use MatCreateSubMatrices first, then use MatGetRow. But I couldn't understand to which extent I should create submatrices. I just need to have all 72 rows as 72 different vectors each having 4 elements. Thanks! Eda
