My Frontier Thesis said...: JJ, now you get to explain this in humanities lingo to mft. As an amateur drummer and percussionist, this "Drum at rest" has grabbed my attention.

What's going on now?; 3/30/2007 1:06 PM
Pepe le Pew said...: You did this with Mathematica, right? I took numerical analysis on it years back. Neat to play with but no code is less maintainable.
One nice application was the inversion of a 19x19 matrix in closed form (ie, non numerical) for the cubic b-spline parametrization of the radial component of an earth model for my thesis. Could have never done this with pen & paper.; 3/30/2007 3:19 PM
Mr roT said...: what do you mean maintainable? you're right that it's a hell of a lot of fun. doing lots of projects with it now. just that pde seem always most picturesque.
you have some nice doc'd code for me? i was thinking of setting up a site.; 3/30/2007 5:45 PM
Mr roT said...: 19 X 19 i do in my head, schmuck; 3/30/2007 5:45 PM
Pepe le Pew said...: what do you mean maintainable?

code that is readily tweakable. Im Mathematica, it is usually easier to rewrite code than maintaining it. For instance, nested if-then-else statements (if i recall were all commas) are the computing equivalent of a messy abortion, coat hanger and all. Compare this with C or Java, with nicely indented code that you can read like a book (and readily modify).

you have some nice doc'd code for me? i was thinking of setting up a site.
No idea where it would be.; 3/30/2007 9:56 PM
Mr roT said...: I see what you mean. Do[expr[i,j], {i,0,NN},{j,0,MM}]makes sense and you have zero chance of ever reading it again.; 3/30/2007 11:03 PM
