it's normal when you run a time consuming prgram in matlab. just wait for a while. my suggestions are: (1) run the program with some similar but small t ests first, then you can get a good estimation of the time of the real one.( 2) add some lines in the code to output some indicators, such as the # of it erations, so you will know what steps it currently on.
Agree. BTW: you'd better write the indicators to a small .txt file because sometimes the matlab program doesn't respond during a large scale calculation.

thanks a lot, it is a great idea to give an output, i do it next time. luckily, the program is not dead, it came out this morning:)
For some matrix computations, Matlab would be as fast as C/FORTRAN.

I don't believe Matlab is good for debugging... because its language is too much flexible, sometimes, you make an error, yet the program is still able to run but give you totally nonsense. I prefer the language that has lower tolerance.

matlab对付5000×5000的matrix如何?用xcorr2命令好像就死机了,老半天没反应。 pentium(R)4 CPU 3.2G,2G RAM.升级一下机器如何?1k一下不带显示器的有什么推荐 ?多谢。
