Crash while starting Matlab 2009b on Snow Leopard
I get a crash while trying to start Matlab 2009b on my Mac laptop. It crashes immediately after opening the initial window. Below is the first part of the crash report. Until I can figure this out, I'm completely dead in the water because I can't run Matlab at all. I can't make any sense out of the traceback to eve... 23 Feb 2010 10:09

Tridiagonal Solver
Basically what I need to do is code a tridiagonal solver and be able to implement it with sparse matrices. Right now I feel my code is a bit off and I am not sure what I need to tweak. So far I have: function x = project2(a,b,c,d,n) for i = 2:n s= -a(i-1)/b(i-1); b(i)= b(i)+c(i-1)*s; d(i)= d(i)+b(i-... 18 Feb 2010 22:56

Reading in and editing an m file
Dear all, I am a beginning Matlab user and trying to do a relatively simple task. I have a series of vectors saved in a file ('vectors.m'). I want to create a new file ('vectors2.m') that is a copy of the first, and search for one vector ('vectorB') and randomly sort the values into two groups (e.g. 'vectorB1' and ... 18 Feb 2010 19:35

Reinterpreting float32 data as uint32
I'm using fread() to read in large binary data files with fixed-size logical records. Each logical record contains ten items, nine of which are float32 data and one of which is uint32 data. For simplicity, I read in a large chunk of data in a single fread() statement, using a "precision" string to store all read data... 19 Feb 2010 18:51
