In-place mm! is not supported for GE matrices. Use QR

I'm test multiplying two matrices like so:

(mm! (ge fac 2 1) (ge fac 1 2) (ge fac 2 2))

Following the tests in the source code:

(with-release [c (ge factory 2 2 [1 2 3 4])]
           (identical? (mm! 2.0 (ge factory 2 3 [1 2 3 4 5 6]) (ge factory 3 2 [1 2 3 4 5 6]) 3.0 c) c))

But I'm getting the following error:

1. Unhandled clojure.lang.ExceptionInfo

How to fix this error?

uncomplicate / neanderthal
