Guide to Secant MATLAB. ... Let us now understand the code of the secant method in MATLAB: ... Explanation of the 'if-else' loop above:.

%% Secant method % If we have two iterates $a$ and $b$, with corresponding function values, % whether or not they exhibit a sign change, we can ...

When secant method is applied to find a square root of a positive number A, we get the formula. pk + 1 = pk − p2k − A pk + pk − 1, k = 1, 2, …. Example. Let us find a positive square root of 6. To start secant method, we need to pick up two first approximations,which we choose by obvious bracketing: x0 = 2, x1 = 3.

When secant method is applied to find a square root of a positive number A, we get the formula. pk + 1 = pk − p2k − A pk + pk − 1, k = 1, 2, …. Example. Let us find a positive square root of 6. To start secant method, we need to pick up two first approximations,which we choose by obvious bracketing: x0 = 2, x1 = 3.

Since we need to remember both the current approximation and the previous one, we can no longer have such a simple code as that for Newton's method. At this ...

When I run this, the loop stops correctly (I think). But it displays wrong number. Following is simple inputs to MATLAB: a= 3*x+4 f(x) = 3*x+4 x(1) = -2 x(2) = -1 loop starts: x(3) = -1.1429 <-----should be the wrong answer, I should get -4/3 as my root. iteration count = 1 <----- which is correct, because the iteration should be 1.
