  • mpsolve - Multiprecision Polynomial SOLVEr
    Software that aims to provide an easy to use (hopefully) universal blackbox for solving polynomials and secular equations.

    Among its features you can find:
    - Arbitrary precision approximation.
    - Guaranteed inclusion radii for the results.
    - Exploiting of polynomial structures: it can take advantage of sparsity as well as coefficients in a particular domain (i.e. integers or rationals).

    It can be specialized for specific classes of polynomials. As an example, see the roots of the Mandelbrot polynomial of degree 2.097.151 computed in about 10 days on a dual Xeon server.

    If you use MPSolve in your research, please cite it as follows:

  • Polynomial Rootfinder repost
    The HP 48 object listed below in ->ASC form is a high-performance polynomial root finder. Those of you who remember the HP 71B Math Pac will recognize this as the same as the PROOT command from that Pac; it is in fact the same assembly-language code, given an RPL front end to operate in the HP 48.
    Found on https://www.hpmuseum.org/forum/thread-10967-post-160700.html#pid160700
    See also http://www.jeffcalc.hp41.eu/emu71/mathrom.html#src for the uncommented source code of PROOT and other functions of the HP71B math pack.

  • Dr. John L. Gustafson: Publications
    Written by one of the foremost experts in high-performance computing and the inventor of Gustafson's Law, The End of Error: Unum Computing explains a new approach to computer arithmetic: the universal number (unum). The unum encompasses all IEEE floating-point formats as well as fixed-point and exact integer arithmetic. This new number type obtains more accurate answers than floating-point arithmetic yet uses fewer bits in many cases, saving memory, bandwidth, energy, and power.

  • How to Convert Temperature (K) to RGB: Algorithm and Sample Code – Tanner Helland (dot) com
    Converting color temperature (Kelvin) to RGB.
    The algorithm provides a high-quality approximation, but it’s not accurate enough for serious scientific use. It’s designed primarily for photo manipulation – so don’t try and use it for astronomy or medical imaging.
