Hi all, I have been trying to use the fminsearch routine to minimize a non-linear least square estimation problem, one in which i will have to give three initial guesses for the parameters but the routine just return the same initial guesses i pass to it so i was thinking if i can get a practical guide as to how fmins... 20 Jul 2010 14:40

multiple paths for same file
Hoi, I have set several breakpoints in a file. Not all of the breakpoints are visually shown by red bullets, so I call dbstatus("-completenames").
