conditional operator

Hi there fellow MATLABers,

I have recently had the following "problem": I wanted to define a
function such as the sinc function (sin(x)/x), which for x->0
approaches 1, but obviously MATLAB throws a division by zero error.
The solution is simple enough (define the function in an m-file, use
an if-statement, and test for the "offending" input). Done that,
works fine.

Here is my question for the community: ideally I would have liked to
define an anonymous function (sinc = @(x) sin(x)/x;), but that does
not allow the if-statement. In C, I would have used the conditional
operator "?", as in ( (x==0)?1:sin(x)/x ).
I am not aware of MATLAB having such a nice tool; does somebody know
a simple way to achieve the same thing?

Dietrich
