secant method

基本解釋

This paper mainly deals with the secant method used on stiffness matrix.
主要說明割線法在剛度矩陣上的應用。
Then the numerical results show that new algorithm effectively overcomes the shortcomings of secant method, and evidently improves the convergent speed, convergent range and algorithm stability.
數(shù)值實驗結果表明，這種算法不僅有效克服了割線法的缺陷，而且收斂速度、收斂范圍和算法的穩(wěn)定性也得到明顯提高。
In this paper, the author applies affine reduced operation to the model based secant method and gives a new method to look for the descent direction for solving unconstrained minimization problem.
