Copying from my comment, as apparently it turned out to solve the entire problem:

double obj(double x)

The function expects a value, not a pointer to a value.

y = coder.ceval('obj',coder.ref(x));

You are passing a pointer to the value, not the value itself.

y = coder.ceval('obj', x);     %just pass the value
