tfidf 是個非常普遍作用在文件檢索的功能，輸入為一個[i*j]的term-frequence的矩陣，輸出為[i*j]的tfidf值-tfidf has been applied on the task of text process. The input of the function is a [i*j] term-frquency matrix. The output is a [i*j] of which element is calculated by the tfidf measu

有限元分析中单元刚度阵组装为整体刚度阵，并且整体刚度阵采用半带宽存储的程序。-Finite element analysis for the overall stiffness matrix assembled stiffness matrix, and the overall stiffness matrix semi-bandwidth storage procedures.

In numerical linear algebra, the Jacobi method (or Jacobi iterative method[1]) is an algorithm for determining the solutions of a diagonally dominant system of linear equations. Each diagonal element is solved for, and an approximate value is plugged
