The "GEE! It s Simple" package illustrates Gaussian elimination with partial pivoting, which produces a factorization of P*A into the product L*U where P is a permutation matrix, and L and U are lower and upper triangular, respectively. The functions in this package are accurate, but they are far slower than their MATLAB equivalents (x=A\b, [L,U,p]=lu(A), and so on). They are presented here merely to illustrate and educate. "Real" production code should use backslash and lu, not this package.

一个基于GTK+的单词数值计算器,1、 按照规则计算单词的值,如果 A B C D E F G H I J K L M N O P Q R S T U V W X Y Z 26个字母(全部用大写)的值分别为 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26,如: WINJACK这个单词的值就为:W+I+N+J+A+C+K=23+9+14+1+3+11=71% HARDWORK=H+A+R+D+W+O+R+D=8+1+18+4+23+15+18+11=98% LOVE=L+O+V+E=12+15+22+5=54% LUCK=L+U+C+K=12+21+3+11=47% ATTITUDE= A+T+T+I+T+U+D+E=1+20+20+9+20+24+4+5=100% 2、对程序的界面布局参考如下图所示,在第一个单行文本框输入一个单词,点击“计算”按钮,按照以上算法计算出该单词的值。 3、如果在最下面的单行文本框输入一个文件路径,此文件每行记录一个单词,那么经过程序计算出各个单词的值,并把结果输出到当前目录下result.txt文件中。如果文件不存在,应该提示错误。

先用C-均值聚类算法程序,并用下列数据进行聚类分析。在确认编程正确后,采用蔡云龙书的附录B中表1的Iris数据进行聚类。然后使用近邻法的快速算法找出待分样本X(设X样本的4个分量x1=x2=x3=x4=6;子集数l=3)的最近邻节点和3-近邻节点及X与它们之间的距离。
