Mathworks.com states 'hist is not recommended. Use histogram instead.' However when I use example given I get the error below. I suspect I don't have the right toolbox, but strangely Google searches don't answer 'which toolbox has histogram' DO I need another toolbox?
X = randn(1000,1); h = histogram(X) Undefined function 'histogram' for input arguments of type 'double'.

It should be in the main toolbox if you are using > R2014b. If you are using an earlier version then it hadn't been introduced in the main toolbox. I don't know if it existed in some other toolbox before then though.

Be careful of the documentation you’re reading! The current online documentation is for R2016a. If you have R2016a, you should have histogram. If you have R2013b or earlier, you won’t.
In your Command Window, type:
doc hist
doc histogram
and see what the Help Browser does.

using R2014a so that explains why histogram doesn't work. Thanks

My pleasure.
The hist function should work well enough for you. There isn’t a lot of difference between them.
