Problem with triplot?

I tried the sample script in the help for triplot

X = rand(10,2); dt = DelaunayTri(X); triplot(dt)

and got the result: "Error using triplot Too many input arguments."

I am puzzled. Any thoughts as to what is happening? Stephen

That could happen if you had your own triplot.m in your path. Check

   which -all triplot

Thanks - that was it - I had an old (ca. 2000) oceanography toolbox that included old versions of triplot of uncertain origin. Deleting these fixed the problem.
