function with xmin causes error

I am supposed to create xmin as a function but no matter what I try MatLab always displays:

Error using minfun
Too many input arguments.

My code looks like this:

function xmin=minfun(x)
n=length(x);
xmin=x1;
    for k=2:n
        if (x(k)<xmin)
            xmin=x(k);
        end
    end
end

I really have no idea where I made a mistake...

The problem is in how you execute the function. You need to go to the command line and type in the function name and the input argument. For example,

minfun([pi exp(2) sqrt(5)])

Oh it's such a stupid mistake. Thank you so much you saved my day. :)
