I don't know if you guys have had experience with the c matrix library meschach. I wanted to use it for matrix inverse/ multiplication etc. And I tried to follow their advice on: Meschach page on wwwmaths
I downloaded the file and tried to run their configure file on a cygwin system and had some strange errors. (./configure: line 2: $'\r': command not found) I also tried with ubuntu and there was a configure: command not found error this time. Does anyone have experience with this library? Also in general how would you install a library?
