The pivot transformation uses the properties on its input and output columns to define the pivot operation 透視轉(zhuǎn)換使用其輸入列和輸出列的屬性來定義透視操作。
In the forth part , the paper uses markowtiz mean - variance analysis in portfolio choice and capital markets and professor zhang zhongzhen pivoting operation to solve portfolio loans 第四部分,文章利用markowtiz的資產(chǎn)選擇理論和張忠楨教授的樞軸旋轉(zhuǎn)運(yùn)算法試圖解決貸款組合問題。
Chapter 1 , making use of the technique of pivoting operation , the technique of sequential systems of linear equations of studying constrained optimization problems and the idea of strongly subfeasible directions method and , several new algorithms for systems of nonlinear inequalities are presented 第一章,借助于轉(zhuǎn)軸運(yùn)算技術(shù),序列線性方程組技術(shù)以及強(qiáng)次可行方向法思想,建立了非線性不等式組的序列線性方程組算法,算法的搜索方向由有唯一解的線性方程組的解及其校正產(chǎn)生。
