thanks for working on this topis, it is a nice idea to extract variables from ODE automatically. I vote also for splitting into two patches and if you have problems with this, I can try it to split them by myself. Anyway, the ODE patch depends on the mtype interface and this interface should

Hi, I got this from the report a problem public bugtracker. I don't know if this is already known but it's a nice example that there is something odd in the symbolics code. I can confirm it in 4.3.5. The script below calculates the eigenvalues for a matrix, M. I want to use 'delta' as a symbolic
