Andrew Nesterov - 2004-05-14 15:47:00
In other words, DFT works exactly like optical grating,
producing a mainlobe of 0th order and a sequence of
mainlobes of higher orders. I even saw several times rainbows
of order 1 and 2. All these...Re: Is Matrix inversion O(N^3)?

I had a good portion of laughter while looking at the
page located by the link below.
If you'd go there and inspect the example C code on
the page, you'll find out why!
Cheers,

John,
Fourier transform works in the space domain exactly as in
the time domain.
A three-element coordinate vector x is an analog of time and
a wave number k is an analog of circular frequency ...Re: data alignment on TI dm642
Andrew Nesterov - 2004-04-08 04:57:00
The warning tells that a local (in your case, a function level) variable,
that is allocated on the stack cannot be aligned. Not sure why though.
File level variables (that are allocated in e.g. .f...Re: Function cos() always give false results in ti-6701 evm but not in software simulator,why?

Andrew Nesterov - 2003-09-19 20:17:00
Martin,
What if reserve space for a global variable (somewhere in .data or .bss
or whatever else, but declare it global) and store it with the context
you have just loaded, perhaps this way you w...
