Deterministic Simulation Issues

Hello,

I’m having a bit of an issue with a deterministic simulation. I can solve for the initial and end values just fine, but the simulation keeps giving me vectors of NaN and telling me that some matrix is nearly singular. I can’t for the life of me figure out why I’m having this issue.

I have attached the .mod file, but it won’t let me attach the .mat file that I call on to set the parameter, initial, and end values. I would be willing to email said file to anyone who is willing to help me. I apologize for the inconvenience as this setup was an attempt to make the results more flexible to robustness checks.

Thank you!

Here is a simpler .mod file with all the values included.

You set mu to 0 in the shocks block, but in the equations you have:

with theta=0.5. This yields 0^-0.5=1/0^0.5=infinity.

Wow, that’s a little embarrassing. Thanks for the help! You’re the best!
