<s id="uo8ky"></s> Excel的強大函數功能，為我們帶來了極大方便，雖然它有200多個函數，但有時我們為實現一項規定的功能，可能用到幾個函數或者采用嵌套函數，這樣應用起來，也不太方便。其實對于我們經常用到的功能，我們可以創建自定義函數UDF(User—defined function)，它的運行與Excel中自帶的函數完全相同。建立自定義函數有以下幾個優點：建立自己特殊的功能和名稱的函數；能將復雜的、嵌套的、多個原有的函數組合在一起，發揮更大的威力。

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.

Java technology is both a programming language and a platform. The Java programming language originated as part of a research project to develop advanced software for a wide variety of network devices and embedded systems. The goal was to develop a small, reliable, portable, distributed, real-time operating platform. When the project started, C++ was the language of choice. But over time the difficulties encountered with C++ grew to the point where the problems could best be addressed by creating an entirely new language platform. Design and architecture decisions drew from a variety of languages such as Eiffel, SmallTalk, Objective C, and Cedar/Mesa. The result is a language platform that has proven ideal for developing secure, distributed, network-based end-user applications in environments ranging from network-embedded devices to the World-Wide Web and the desktop

This project demonstrates the use of secure hash functions technique to implement a file encryption / decryption system. This implemented application can encrypt / decrypt multiple files on the fly using a password. The password supplied by the user is used as the source message from which the hash code (key) is generated using the SHA algorithm. Then this key is used to enctypted the data in the file(s). This key is stored in the encrypted file along with the encrypted data.
