I'm new to matlab, and just downloaded the program using all of the defaults in the installer. While going through the tutorials I noticed that inv(a), where a is a matrix, was not giving the correct answer. I attached a screenshot of my command window. I've restarted the program several times, but got the same answer each time I tried this calculation.
Did something go wrong with my download? Or is there a way to fix this without having to reinstall? Hopefully I'm overlooking something simple. Any advise would be appreciated.
Thanks!
