create histogram

hi,
what could be the code to create a histogram out of vector ? for example, let's take a normalized random serie
V=normrnd(0,5,50,1);
I'd like to write the code to create a histogram out of these 50 lines. Obviously in this case the histogram should very much look like a bell curve mean 0 std deviation 5, and the idea could be applied to any type of data
many thanks in advance

Check out the Matlab function HIST.

Hi, do you mean beside?

hist(V)

that was so simple... thanks! the File / generate M-file provided such a complicated answer without using the hist function

no, in fact the Generate M-file got me lost in a complicated solution using patch and other weird -to me- stuff, while hist is so nice and simple. thanks anyway, and have a good year

If you used HIST and then generated a file, then yes -- how is "Generate
M-file" supposed to know that the graphics from which it's being asked to
generate code was created from a call to HIST? It doesn't. All it knows is
that there are some graphics objects (which you and I know were created by
HIST) in the figure, so it generates code to faithfully reproduce those
graphics objects.
