[Help-glpk] enable/disable rows/cols for a problem

[Sebastien . deMentendeHorne]

Hi,

I would like to temporarly delete a row/column in a LP problem, solve it,
and add the row/column again.
I could do it with 
        - glp_delete_cols/rows
        - solve
        - add back the col/row
However, this is tricky (numbering scheme is changed, must add the col/row
multiple time with the same information)
Is there a function that apply a kind of mask over activity of cols/rows ?

Thank you,

PS: i'm using glpk with guile (Scheme) via SWIG and it works great! Very
nice package
