Higher order differential equations can also be recast as systems of first-order equations. Shooting methods provide a good approach to (two-point) boundary value problems. The second initial condition (typically the slope) is an unknown and we solve for that unknown to ensure the final point ...

This study explores the potential of utilizing hardware built for Machine Learning (ML) tasks as a platform for solving linear Partial Differential Equations via numerical methods. We examine the feasibility, benefits, and obstacles associated with this approach. Given an Initial Boundary Value Problem...

Autodiff does not work on Python functions. When applicable, either define the derivative function as a Julia function or set the algorithm to use finite differencing, i.e. Rodas5(autodiff=false). All default methods use autodiff. Delay differential equations have to use Julia-defined functions ...
