Most people don't need more than a handful of linear algebra operations (or think they don't), so Breeze and most wrappers of LAPACK or similar libraries don't implement or wrap them. But most people who work seriously on num

Improvements to our LuaJIT benchmarking are currently being discussed in https://github.com/JuliaLang/julia/issues/14222 . LuaJIT 2.1 is significantly faster than LuaJIT 2.0, but until now I haven't had a

> Your claim is fallacious, because a floating-point value denotes a range of the real number line, whereas you're insisting that, no, it stands for its literal value: the absolutely precise rational number that lies at the center o

It was either 'go with the title or come up with another one', and I was too tired to argue. By the way, the paper was really an excuse to document this IJulia notebook. http://nbviewer.ipython.org/urls/raw.gi

Agreed, not really a prediction, but rather a projection. Still, it surprises me that few people take the trouble to make the connection between the spectra and the perceived colors. Seems like photochemistry and colorimetry don't inte

No, I put that in the first cell. You can take it out of the notebook if you want.

Is this so unreasonable? I needed to curry the function to sweep over the temperature T. And if you take out the units, it's simply pointwise multiplication of two functions.

Ah here we go. The spectrum for Rhodamine B is noisy and it's throwing the normalization heuristic off. I've added a moving average filter and zeroed out some small noise in the >600 nm range and the colors make more sense now.

There's something odd about how my normalization heuristic behaves with this particular spectrum. I haven't yet looked into it.

It depends on what kind of user you are. If you are comfortable with the risks and rewards of being an early adopter using bleeding-edge tools, then by all means try Julia. If you need the stability and functionality of a mature platform, t
