I do not know why it wouldn't work in 2014b. Something similar was reported for 2013b though it worked in previous versions and in 2014a. I do not use 2014b so haven't tested. Perhaps a Matlab issue that will be ironed out.
This is a very useful script. Thank you!
However, I can get it to work in Matlab 2014a, but it doesn't work in Matlab 2014b trial version. The bars display properly but the error bars didn't. Do you know what the problem is? Thank you!
