Error that makes no sense at all

Suddenly the histogram function doesn't generate plots. I tested it with this:

>> x = randn(10000,1);
>> h = histogram(x)
Error using histogram
Too many input arguments.

What gives?

What is the result of

which histogram

?

At a guess you have probably created your own function with that name

[Stephen23]

Better, because it shows shadowed functions:

 which histogram -all

[Adam]

True, although I tend not to suggest that since any not shown by the command without '-all' are hidden anyway so are not the active function.

[John D'Errico]

It is just personal preference though. Myself, I like the -all appendage, for what I consider a good reason. That makes it clear there still is a histogram function, but that it has been shadowed. It might help the user to understand what they have done.

In rare cases the difference might be important too, perhaps helping to track down the event someone has done something deviously bad, and overwritten the supplied version of histogram.m with their own code.

[Stephen Thompson]

Indeed I had something added to my path with a histogram.m in it.

[Steven Lord]

In that case, Adam can you submit your comment as an answer so Stephen can accept that answer and give you credit?
