Monthly Math development meeting: 2/17/2022, 10 am EST

We’ve been having monthly Math meetings on the third Thursday of the month. The next one is Thursday, February 17, 2022, at 10 am EST (1500 UTC).

This will last no more than one hour; if we need more time, we will schedule additional time.

This meeting is open to all those that currently contribute to the Math library or that would like to contribute to the Math library.

The direct Zoom link is: Launch Meeting - Zoom

I have a Google Calendar event set up if anyone wants it on their calendar. Please DM me with your Google handle if that’s of interest.


  • this is a chance to collaborate and coordinate efforts. We’re expecting everyone to be kind and courteous. And patient. We have a team with diverse backgrounds.
  • impactful decisions will not be made at these meetings. That will continue to be done online on these forums. The meetings are a good time to discuss and get on the same page, but the decision making will be done online where we can include the opinions of others that can’t make the meeting.
  • important discussions that happen at the meeting will be communicated back online on these forums. If they don’t make it back here, it wasn’t important. No one will be penalized for not being present at a meeting.

If there’s anything you know you want to talk about, please post here. This is a good time to request help from others if there’s expertise that you need.

Tagging people that may be interested: @Funko_Unko, @storopoli, @stevebronder, @jgaeb, @spinkney, @Bob_Carpenter, @rok_cesnovar, @wds15, @WardBrian

I’m on. If anyone has trouble getting in, please post here or dm me.

@WardBrian and @Niko are here!

Brian has questions about the state of complex in Math.

@stevebronder joined.

We’re looking at code… at matrix multiply now.

We talked about complex a little more. @WardBrian wanted to know how much of the Math library could handle complex types and wondering if it was known how much. We all got to the conclusion that it isn’t common knowledge and we’ll have to put in effort to get a handle on it.

@Niko is asking a question about his custom ODE solver and a potential memory leak. We talked through some of the details of allocation and recover memory at a high level.

Meeting adjourned!

Oh, yeah, that’s the code if anyone is interested or for future reference: ode_solver.hpp · GitHub
