A matrix in a vector for no good reason.

So, I've been rerunning this program I designed last month. It takes a random 256 pixel square out of each of 4212 images in a calibrated database of photographs. It determines which of 108 frequency-space filters would give the biggest response to that sub-image. That's 9 frequencies (the lowest and two highest never have maximal responses, but they're there as buffers so no energy is ignored). For some reason, I wrote the spectral filtering function so that it would return the filter coefficients in a 108 entry vector instead of a 12x9 matrix. I don't know why I wrote it this way. This means that every time I want to do something different with the data in the driver function, I have to sit and think again about how to find the right entry in the vector. This is really irritating, but I don't go back and slightly rewrite the analyzer function, because I don't want to do a bunch of back-and-forth fixing to adjust for the function fix. I leave the function messed up and go ahead and just make things difficult for myself in handling the output data. I don't know why. Also, my tooth-hole hurts.

  6. didn't melody decode the code last time? is this a code or a monster attack?

  7. no, just for fun (mostly mine, honestly!) no attack...just a fun cryptogram. it's very familiar, except the numbers. just giving something new to read.

  8. not fair, i figured n, then m, then x and q, then o and y; then it popped out and i knew what it was; then, realized it was subtly misdone to mislead me, and 'tapping' was spelled 'tamming' and 'taooing' in the conversion, and 'muttered' was 'muttereu'. yar.

    oh, that's funny! I tried to outsmart you with my stupidity! i didn't double check this one! you got it. I wanted to alter the structure, because i figured that would give it away, but i guess i screwed up the code! my stupidity leads me to genius!

    I just solved it! Oh, that's terrible! I'm a terrible person! If I ever post another one, I'll be sure to double check it! I'm so dumb.
