Google Patents US20100158162A1 - Qr decomposition detection device and method supporting interference whitening pdf).I've personally found the "help" mechanism in Sage quite valuable.US20100158162A1 - Qr decomposition detection device and method supporting interference whitening See also Sage Documentation, where you can find tutorials, manuals, references, etc. More details available here Wikipedia on Sage. Graphics: Matplotlib, Tachyon3d, GD, Jmol Graphical Interface: Sage Notebook, jsmath Numerical computation: GSL, SciPy, NumPy, ATLAS Linear Algebra: ATLAS, BLAS, LAPACK, NumPy, LinBox, IML, GSL (You can also peruse sample "Worksheets" from "notebooks").Īnother "plus" about Sage Notebook is that you can create folders, save your work, etc, on-line, and can then thus access it (when on-line again) and pick up where you left off at another time.Īrbitrary Precision Arithmetic: MPIR, MPFR, MPFI, NTL, mpmathĪrithmetic Geometry: PARI/GP, NTL, mwrank, ecm You can create your own account if you scroll down to the bottom of the webpage linked immediately above. I'm not sure about its graphing capabilities though it does seem to come equipped with some graphing functionality. (see more programs listed below), and you can program, as well (Python?). I can't speak for hicalc (I've not heard of it!) but IMO, a good choice would be Sage Notebook: it integrates a whole bunch programs: GAP, R (statistics), Pari, etc. That may help you ultimately determine what works best for YOU! Various systems are listed in tables, each identifying cost, features, etc. Added: I found the Wikipedia article Comparison of Computer Algebra Systems from a link on Sage's site.
