I am trying to use the histogram function, and even the basic MathWorks demonstration does not work in my Matlab

x = 2*randn(5000,1) + 5;
histogram(x,'Normalization','pdf')

I get the following mistake: Undefined function 'histogram' for input arguments of type 'double'.

Error in TEST2 (line 2) histogram(x,'Normalization','pdf') >>

Those commands produce a histogram for me (R2015b). The histogram command is relatively new, introduced a couple versions ago. Do you have an older version? What do the commands

which histogram

and

doc histogram

do for you?

I got this to work

data = 2*randn(5000,1) + 5
hist(data)
Thank you

At the bottom of the online documentation page for HISTOGRAM it says "Introduced in R2014b".
