raptop changed the topic of #principia to: READ THE FAQ: http://goo.gl/gMZF9H; The current version is Fréchet. We currently target 1.5.1, 1.6.1, and 1.7.x. <scott_manley> anyone that doubts the wisdom of retrograde bop needs to get the hell out | https://xkcd.com/323/ | <egg> calculating the influence of lamont on Pluto is a bit silly… | <egg> also 4e16 m * 2^-52 is uncomfortably large

neph. — Odd request. Any pointers on how to implement a finder of spectral radius for a n by n matrix?
<discord->
neph. — I'm trying to estimate my conditioning, but doing that is providing a bigger challenge that writing the solver itself
<discord->
neph. — Wait, is the matrix 2-norm = sqrt of the spectral radius equivalent to the sum of the 2-norms of each row?

neph. — Wait, is the matrix 2-norm = sqrt of the spectral radius equivalent to the product of the 2-norms of each row? (edited)

Butcher. — @Standecco Have you looked at the Principia code btw?
<discord->
Standecco. — @Butcher it's in C++
<discord->
Standecco. — it's also enormous

Butcher. — The line draw is in the C# adapater
