Re: [ojAlgo-user] v27

[Anders P. <an...@op...>]

Worked hard on improving performance on BasicMatrix operations (which  
means I had to optimise everything else).

What I measure is how much faster/slower PrimitiveMatrix is compared  
to JamaMatrix, and the same correspondingly for decompositions.

If "primitive" on an average used to be (v25) 5% to 10% faster than  
"jama", it is now roughly 25% faster.

With decompositions the main improvements seem to be where "primitive"  
were already performing very well. The QR and SingularValue  
decompositions used to be 12 and 8 times faster than "jama" on tall  
matrices. Now they are 15 and 11 times faster.

Try it yourself!
