Discretize a topographic profile described by a degree-9 polynomial

I have a 2D topographic profile of sand dunes (height vs. distance) described (in a simplified way) as a polynomial. I need to discretize it into 37 chunks. How do I do that? (I got the polynomial by using "fit" and "coefvalues")

Use feval to evaluate the function at the desired x locations.

discrete_polynomial_values=feval(fitted_polynomial,x_positions);
