Nested Function and Function Handle Example

Find a zero of a cubic polynomial x^3+b*x+c for different values of b and c near x0.

Try:

function y = findzero(b, c, x0)
options = optimset('Display', 'off'); % Turn off Display
y = fzero(@poly, x0, options);
    function y = poly(x) % Compute the polynomial.
        y = x^3 + b*x + c;
    end
end

x = findzero(2, 3.5, 0)
