Re: [sympy] Add meijerg = False in dsolve

Disabling integration would be a neat solution! However, as Aaron stated, dsolve() hangs when using all_Integral. What would be the best way to proceed? Would a flag integrate=False be an appropriate issue to start? Op dinsdag 17 januari 2023 om 19:38:48 UTC+1 schreef Jeremy Monat: > Seems like

Re: [sympy] Add meijerg = False in dsolve

Seems like the all_Integral hint might work : The simplest way to disable integration is with the all_Integral hint because you do not need to know which hint to supply: for any hint with a corresponding _Integr

Re: [sympy] Add meijerg = False in dsolve

Yes. I was going to mention that to do this, you should disable integration. Right now, the only way to do this is to get the specific hint and add "_Integral" to the end. Unfortunately, classify_ode hangs on this differential equation (it gets stuck in the solve() call in the nth algebraic matcher

Re: [sympy] Add meijerg = False in dsolve

It should be possible to disable evaluation of the integrals by using Hint Functions ending with _Integral . I recall Aaron Meurer mentioned that it would be nice to have a simpler way of setting that flag. Je

[sympy] Add meijerg = False in dsolve

Hi there, When solving differential equations with Heaviside functions, a meijerg function appears in the outcome, while a (simpler) expression is possible as well. For example a beam problem: *import sympy as spw = sp.symbols('w', cls=sp.Function)x = sp.symbols('x')C1, C2, C3, C4 = sp
