Spend a lot of time solving computer problems.
About 10 years experience to work with PC, Mac, Unix, Internet.
Well, this is the old profile written back in 1999, when I registered on EE and started answering questions. I was too lazy to change it for a long time. Gosh, it's 10 years actually!
Currently I'm more interested in Matlab programming to use it mostly for biological data analysis. I found this zone quite new but very exciting with a lot of interesting questions. Will try to be helpful there.
Sometimes it helps if you let us know your Matlab version, OS and which toolboxes you can use.
As most of experts here I will not make your homework, but will try to give you some hints and directions.
See you there!
