Description. Y = sec (X) returns the secant of the elements of X. The sec function operates element-wise on arrays. The function accepts both real and complex inputs. For real values of X, sec (X) returns real values in the interval [-∞, -1] and [1, ∞]. For complex values of X , sec (X) returns complex values.
Y = sec(X) returns an array the same size as X containing the secant of the elements of X . Examples. Graph the secant over the domains and . x1 = -pi/2+0.01: ...
Depending on its arguments, sec returns floating-point or exact symbolic results. Compute the secant function for these numbers. Because these numbers are not ...
Secant method is used to find the root of any polynomial function · As there is no direct function for the secant rule in MATLAB, we define the code or logic for ...
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.
14.09.2019 · Matlab code for secant method. 5.0 (2) ... method is a root-finding algorithm that uses a succession of roots of secant lines to better approximate a root of a function f. The secant method can be thought of as a finite-difference approximation of Newton's method.
Secant Function. The secant of an angle, α, defined with reference to a right angled triangle is. sec ( α) = 1 cos ( α) = hypotenuse adjacent side = h b . The secant of a complex argument, α, is. sec ( α) = 2 e i α + e − i α .
25.03.2018 · Add a function of secant method. You can use either program or function according to your requirement. Also changed 'inline' function with '@' as it will be removed in future MATLAB release. Updated the mistake as indicated by Derby. Added a MATLAB function for secant method. You can use either program or function according to your requirement.

Y = sec(X) returns an array the same size as X containing the secant of the elements of X . Examples. Graph the secant over the domains and . x1 = -pi/2+0.01: ...
20.02.2015 · The complete calculation and iteration of secant method (and MATLAB program) for the given function is presented in the table below: Thus, the root of f( x ) = cos( x ) + 2 sin( x ) + x 2 as obtained from secant method as well as its MATLAB program is -0.6595.
At here, we write the code of Secant Method in MATLAB step by step.MATLAB is easy way to solve complicated problems that are not solve by hand or impossible to solve at page. MATLAB is develop for mathematics, therefore MATLAB is the abbreviation of MATrix LABoratory.. At here, we find the root of the function f(x) = x 2-2 = 0 by using Secant Method with the help of MATLAB.
I have perfomed the Secant method in MATLAB as follows: %Implementation of the secant method. function c = secant2(x0, x1,eps) format long e fx0 = f(x0); fx1 = f(x1); if abs(fx1) < abs(fx0), %c is the current best approx to a root.
Secant method is an iterative tool of mathematics and numerical methods to find the approximate root of polynomial equations. During the course of iteration, this method assumes the function to be approximately linear in the region of interest. Although secant method was developed independently, it is often considered to be a finite difference approximation of…
This MATLAB function returns the secant function of X. Secant Function for Numeric and Symbolic Arguments. Depending on its arguments, sec returns floating-point or exact symbolic results. Compute the secant function for these numbers.
