secant line

基本解釋

A secant is defined as line passing through two points of the curve.
割線(xiàn)的定義是一條通過(guò)曲線(xiàn)上兩點(diǎn)的直線(xiàn)。
A new damping estimation method, the secant line method, was presented, that is based on the distance of neighbor peaks and valley of oscillation.
提出利用相鄰波峰和波穀之間距離估計(jì)阻尼比的割線(xiàn)方法。
Especially, as com-pared with the 0.618 method and the parabolic function-fitting method, the double-secant line method makes the efficiency of the unidimensional search raise obviously.
特別是雙割線(xiàn)法與0.618法和拋物線(xiàn)插值法相比。可使一維搜索的傚率明顯提高。
