Error calling ezplot script

Hi, when I run this simple script:

syms u x

u = x;

ezplot(u)

I get the following error:

Error in sym/ezplot (line 61) h = ezplot(fhandle(f));

Error in test (line 4) ezplot(u)

Why?

Thanks

I have found my error.

I had a code in one of my directories that was titled ezplot.m that I created years ago.
