Re: indexing in octfile

[Paul Thomas]

Brian,

The class functions insert,

Matrix & insert (const Matrix &a, int r, int c)
Matrix & insert (const RowVector &a, int r, int c)
Matrix & insert (const ColumnVector &a, int r, int c)
Matrix & insert (const DiagMatrix &a, int r, int c)


fill

Matrix & fill (double val, int r1, int c1, int r2, int c2)


and extract

Matrix extract (int r1, int c1, int r2, int c2) const 
Matrix extract_n (int r1, int c1, int nr, int nc) const 


do what you want, rather more naturally than assignment.
