Multiplying Function Handles in Product of Sequence application

Hi

I have the following equation that I need to code up as a single function.

The output function handle would contain the function for the passed value of k.

I was planning of making individual function handles for each value of k and then multiply them in a FOR loop, but that does not seem to work. Any ideas?

Thanks,

Hasan

function [li]=lagrange(x,i) c=x(i); x(i)=[]; syms X; f(X)=prod( (X-x)./(c-x)); li=f(X); end
