Why is igamma undefined?
显示 更早的评论
Hi,
Does anybody know why "igamma" function is not defined, while the symbolic toolbox is already installed. I can define symbolic variables and use gamma function by the way.
Thanks, Bo

Possibly your MATLAB is too old to have igamma() . Please see http://www.mathworks.com/support/solutions/en/data/1-4TW73U/index.html?product=SM&solution=1-4TW73U

igamma is a MuPad function.
To use it, open a MuPad notebook and you can see the doc for it in there:
mupad
Else look at doc gammainc
