"The Secant method is a numerical technique used to find the root of a function. Unlike the bisection method, this method employs two initial values (x₀ and x₁) instead of an interval start, and then ...

The Secant method is an iterative method for finding the roots of a continuous function of one variable. This method is similar to the Newton-Raphson method for finding roots. In the Newton-Raphson ...

In this paper, we provide and analyze a new scaled conjugate gradient method and its performance, based on the modified secant equation of the Broyden-Fletcher-Goldfarb-Shanno (BFGS) method and on a ...

We present a gradient-based algorithm for unconstrained minimization derived from iterated linear change of basis. The new method is equivalent to linear conjugate gradient in the case of a quadratic ...

Abstract: In this paper a new spectral unmixing method for hyperspectral images is introduced. In this method, the unmixing problem is modeled as an optimization ...

In trigonometry, the secant function, commonly abbreviated as sec, is the multiplicative inverse of the cosine function. In other words, sec refers to the ratio of the hypotenuse to an adjacent side ...
