the api doesn't exist yet but you can use the low level lapack

`?potri`

routine family for it.the docstring of

`sp.linalg.lapack.dpotri`

is as followsthe most important is the

`info`

output. if it is zero that means it solved the equation succesfullyregardless of positive definiteness. because this is low-level call no other checks are performed.also if you compare the speed

so you get a quite nonnegligible speed benefit. if you are working with complex numbers, then you have to use

`zpotri`

instead.the question is whether you need the inverse or not. you probably don't if you need to compute

`b⁻¹ * a`

because`solve(b,a)`

is better for that.
