Hi,

I’m starting a project involving calculating neutron guide positions where the positions are defined by 5 cam based movers. The position calculations involve 5x5 matrix multiplication and inversions, and some of the matrix elements are trigonometric functions. 

I’m prototyping the calculations in Python, but does anyone have advice on how to implement the calculations in an EPICS database? My first thought is to use aSub records (or a custom record) linking to GSL libraries. 

I suspect similar work is routinely done on accelerator controls?

Cheers,
Matt
