comparison trunk/matlab/bmm/carfac/CARFAC_Close_AGC_Loop.m @ 534:95a11cca4619

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add CARFAC_Design_Doc.txt, CARFAC_Run_Segment.m, and some renames; rename various variables to be more parallel; clean up init code and such.
