Re: Matrix software for the 41 Message #3 Posted by Angel Martin on 22 May 2009, 1:54 a.m., in response to message #2 by Raymond Del Tondo
I agree with Raymond, the Advantage's implementation is better - just because they (legally) copied the CCD's from the scratch. They (HP, that is) also added a few important utilities also in MCODE, which were sorely missing in the CCD.
In fact a Matrix-less version of the CCD Module is what I decided to do once the superiority of the Advantage in this area was clear. I took them all off and replaced them with more general-purpose functions, in an 8k module - the "Modified CCD", also at TOS.
Raymond's OS/X is of course an absolute must to have on every system, a 4k jewel with all the great OS extensions from the CCD.
I wrote a few more matrix routines using the Advantage and the Sandmath functions, they may be interesting to you as well. They're in the upper 4k of the SandMath_3 module, available at TOS. One of them I fondly remember was a brute-force eigenvalues solver using the Advantages SOLVE function, where the characteristic equation to solve involves of course calculating the determinant on each iteration... fun to watch.
Best,
