Witryna2 paź 2024 · What do you mean by 'find the values of the polynomials'? Does it mean you want to interpolate your data with a polynomail p and evaluate the value of the polynomial for a given x, p_val = p(x)? If so, you may check here. There is a bunch of examples in different languages, you can see how you change that for MATLAB. –
WitrynaSo if f(x) is approximated with a linear polynomial then the function value at any point x can be calculated by using f(x) @ P 1 (x) = f(x 0) + (x - x 1) f [x 0, x 1] where f [x 0, x 1] is the first divided difference of f relative to x 0 and x 1. Similarly if f(x) is a second degree polynomial then the secant slope defined above is not constant but a linear function … rtc branch 224 quezon cityWitryna16 sie 2024 · This is the same polynomial but you just find it in different ways. It's always better to have different ways because that way you have a lot more options. For example, if you want to have an easy formula for the remainder of the interpolation then it is much better to work with Newton's method. rtc branch 23 manila contact numberWitrynaDivided differences are of the form (f(x1)-f(x0))/(x1-x0).
