How many transistors at minimum do you need to build a general-purpose computer? My guess is that I have my error variable wrong in the cycle? ( | The secant method is similar to the false position method except that the two most recent values of x (x 2 and x 3) and their corresponding function values [f(x 2) and f(x 3)] are used to obtain a new approximation to the root instead of checking values that bound the root. As can be seen from the recurrence relation, the secant method requires two initial values, x0 and x1, which should ideally be chosen to lie close to the root. n My MATLAB code is the following . ( 1 The secant method is an algorithm used to approximate the roots of a given function f. The method is based on approximating f using secant lines. ( This looks like a variation of the Steffensen method, known for its close relation to Aitken's delta-squared process. The secant method thus does not require the use of derivatives especially when is not explicitly defined.
