因为不全为零三角位于系数矩阵的右上角,所以 也叫做(左)上三角(Upper triangle )矩阵,记作 ,原方程 变成了 。 四、矩阵乘法与消元 矩阵乘法一般指的是矩阵间的乘法。我们将从矩阵乘法的角度来考虑上述消元过程。 4.1 向量的线性组合 解析几何中,向量的坐标表示是这样的: ,向量就是向量,矩阵就是矩阵,向量没...
之前说过轴的选择是快速排序法的效率关键之一,在这边的快速排序法的轴选择方式更加快了快速排序法的效率,它是来自演算法名书 Introduction to Algorithms 之中。 解法: 先说明这个快速排序法的概念,它以最右边的值s作比较的标准,将整个数列分为三个部份,一个是小于s的部份,一个是大于s的部份,一个是未处理的部份...
