WebQuestion: Write a MATLAB function, of the form: function int =my_trapz(f, a, b, n) where int is the trapezoidal rule answer to: f(x) dx and the interval from a to b is divided into n … WebThe Gaussian quadrature chooses more suitable points instead, so even a linear function approximates the function better (the black dashed line). As the integrand is the polynomial of degree 3 ( y(x) = 7x3 – 8x2 – 3x + 3 ), the 2-point Gaussian quadrature rule even returns an exact result. In numerical analysis, a quadrature rule is an ...
