I am using a 2- dofs system, please see attached.Can the ODE be solved as it written? I can find plenty of info/tutorials, etc on ODE but never with the matrix notationThanksRegards Thu, 03 May 2018 14:01:50 GMT https://www.ptcusercommunity.com/t5/Mathcad/Solve-ODE-in-matrix-form/m-p/197185#M77247 JBlackhole 2018-05-03T14:01:50Z Re: Solve ODE in matrix form? https://www.ptcusercommunity.com/t5/Mathcad/Solve-ODE-in-matrix-form/m-p/197186#M77248 <HTML><HEAD></HEAD><BODY><P>Try this</P><P><IMG class="jive-image image-1" src="https://community.ptc.com/legacyfs/online/109115_pastedImage_1.png" style="max-height: 900px; max-width: 1200px;" /></P></BODY></HTML> Mon, 28 Nov 2016 12:43:51 GMT https://www.ptcusercommunity.com/t5/Mathcad/Solve-ODE-in-matrix-form/m-p/197186#M77248 Fred_Kohlhepp 2016-11-28T12:43:51Z Re: Solve ODE in matrix form? https://www.ptcusercommunity.com/t5/Mathcad/Solve-ODE-in-matrix-form/m-p/197187#M77249 <HTML><HEAD></HEAD><BODY><P>Thanks.
