Description (last modified by )
- In method
solve
of classIntegratedCurve
, the step of integration needs to be evaluated numerically (usingnumerical_approx
) before calling any algorithm, in order to allow it to be an expression such aspi
. - In method
solve
, when using Bulirsch-Stoer algorithm ('bsimp'), methodode_solve
was called in a wrong way. - 'Bulirsch' was misspelled in documentation.
- Minor corrections were made regarding
rk4_maxima
being the default algorithm of methodsolve
.

comment:3 Changed 3 years ago by
I feel like the fact that the corresponding solve
function does not numerically evaluate such expressions is a bug that deserves its own ticket and (independent) fix. Subsequently, I would remove those changes that work around it.
I cannot comment on the second point, so someone else will have to review that.
comment:4 Changed 3 years ago by
The changes look good to me and I agree with comment:3.
Besides, in the documentation of IntegratedCurve.solve
, shouldn't it be mentioned that the default method (corresponding to method=None
) is rk4_maxima
?

Replying to git:
Thank you for your comments.
Corrections did have to be made about rk4_maxima
being the default algorithm of method solve
, and the numerical evaluation of the step is then maintained until another ticket allows to remove it.
