Initial values in init are the values of the ODE function(s) evaluated at x1. - intvls is the integer number of discretization intervals used to interpolate the solution function. The number of solution points is the number of intervals + 1. - D is a vector function of the form D(x,y) specifying the right-hand side of the systemOptions:- AbsTol - absolute tolerance parameter, default value 10⁻⁷.- RelTol - relative tolerance parameter, default value 10⁻⁴.Links:1.

Let me know if you need anything else!All the bestFrancescoEdited by user 02 December 2020 18:46:19(UTC)  | Reason: Not specified Veniamo da molto lontano e andiamo molto lontano! Palmiro Togliatti
 uni #3 Posted : 02 December 2020 23:49:33(UTC) Rank: Advanced MemberGroups: Registered, Advanced MemberJoined: 10/11/2010(UTC)Posts: 1,165Was thanked: 1008 time(s) in 585 post(s) The problem is in the X-Y Plot plugin. It cannot display the input data because it is outside the normal bounds. Also in the document somehow the min and max values of the axis are the same, which also results in an error. It will take a time to fix this. I haven't tested the plugin on bad data much. Russia ☭ forever Viacheslav N. Mezentsev 💰 Support me for plugins development: https://yoomoney.ru/to/410013245578758

Function name is lsoda. Library name is LSODA. It is a part of LSODE (Livermore Solver for Ordinary Differential Equations).Not ISODA. Use correct names. Russia ☭ forever Viacheslav N.
