dassl

[lgm]

Dear Sir,

is it possible to choose vectors for the absolute and relative tolerance
in dassl_options and how ?

If it's not possible yet, I would like to remark that it should be possible
because the dassl.f included in octave offers this opportunity and it is
necessary for solving differential-algebraic equations of index higher than 1.
Unfortunately, I'm not experienced enough in programming to do it personally.

Yours sincerely
