#10946: Add dt to system arguments
 Reporter: ilja.j.honkonen@… | Owner: karsten
     Type: Feature Requests | Status: new
Milestone: To Be Determined | Component: odeint
  Version: Boost 1.57.0 | Severity: Problem
 Keywords: |
 A popular algorithm for calculating the change in velocity of a charged
 particle in a magnetic field (1) requires the length of the time step
 while integrating (dx/dt := f(x,t,dt)) and cannot be used with odeint as
 far as I could tell so I suggest modifying the definition of system from
 sys( x , dxdt , t ) to sys( x , dxdt , t , dt ). Some enable_if magic
 should allow all existing code using the current API to work.

 (1) Equations 25 and 26 in
