Audit usage of linalg.inv #454

Open rileyjmurray opened 3 weeks ago

rileyjmurray commented 3 weeks ago

There are 90 instances of the string "linalg.inv" in the pygsti repo (at time of opening this issue). Explicit matrix inversion is rarely needed in numerical algorithms. Alternative methods (which depend on the context) are usually faster and more stable than explicit inversion. I'm opening this issue so I remember to address it at some point.
