I have a symmetric matrix B (17x17), and a (17x17) square matrix A. If do the following matrix multiplication I SHOULD get a symmetric matrix, however i don't. The computation required is: C = t(A)%*%B%*%A here are some checks for symmetry > (max(abs(B - t(B)))) [1] 0 > C = t(A)%*%B%*%A > (max(abs(C - t(C)))) [1] 3....

Do we have a standard icon and/or glyphs identified for GUI-based applications? I'm adding Vorbis support to CDMaster32 and I'm finding I'm in need of 17x17 glyphs (.bmp) to graphically show progress of OGG files. Has anyone thought about this? If not I was thinking of modifying/reducing the Xiphophorus "fish" logo to use in my application; however, since the xiph www site claims these are both trademarked and copyrighted; I wondered what t...

...o judge the real quality. SNR, especially on a single sample, can be very misleading.

I has two ALUs with 17x17 bit MACs, and it has an instruction that does this: ACy = M40(rnd((ACx >> #16) + (uns(Xmem) * uns(Ymem)))) I never quite understood this, so I went of and looked at the manuals. It can multiply the low half in one cycle, then shift and add it to the high half in a second cycle. And, in...
