Excel的强大函数功能，为我们带来了极大方便，虽然它有200多个函数，但有时我们为实现一项规定的功能，可能用到几个函数或者采用嵌套函数，这样应用起来，也不太方便。其实对于我们经常用到的功能，我们可以创建自定义函数UDF(User—defined function)，它的运行与Excel中自带的函数完全相同。建立自定义函数有以下几个优点：建立自己特殊的功能和名称的函数；能将复杂的、嵌套的、多个原有的函数组合在一起，发挥更大的威力。

A heap is a binary tree satisfying the following conditions: This tree is completely balanced. If the height of this binary tree is h, then leaves can be at level h or level h-1. All leaves at level h are as far to the left as possible. The data associated with all descendants of a node are smaller than the datum associated with this node.

SuperLU is a general purpose library for the direct solution of large, sparse, nonsymmetric systems of linear equations on high performance machines. The library is written in C and is callable from either C or Fortran. The library routines will perform an LU decomposition with partial pivoting and triangular system solves through forward and back substitution. The LU factorization routines can handle non-square matrices but the triangular solves are performed only for square matrices. The matrix columns may be preordered (before factorization) either through library or user supplied routines. This preordering for sparsity is completely separate from the factorization. Working precision iterative refinement subroutines are provided for improved backward stability. Routines are also provided to equilibrate the system, estimate the condition number, calculate the relative backward error, and estimate error bounds for the refined solutions.

This taglib contains tags used to create struts input forms, as well as other tags generally useful in the creation of HTML-based user interfaces. Many of the tags in this tag library will throw a JspException at runtime when they are utilized incorrectly (such as when you specify an invalid combination of tag attributes). JSP allows you to declare an "error page" in the <％@ page ％> directive. If you wish to process the actual exception that caused the problem, it is passed to the error page as a request attribute under key org.apache.struts.action.EXCEPTION.

The Software Engineering Institute’s (SEI) Capability Maturity Model (CMM) provides a well-known benchmark of software process maturity. The CMM has become a popular vehicle for assessing the maturity of an organization’s software process in many domains. This white paper describes how the Rational Unified Process can support an organization that is trying to achieve CMM Level-2, Repeatable, and Level-3, Defined, software process maturity levels.
