基于MATLAB函数库增强VB数值计算能力的研究

Research on Intensifying Numerical Computation Ability in VB Based on MATLAB Function Library

针对VB数值计算能力不足,不利于算法开发和程序发布的状况,文章在介绍了MATLABC/C++数学函数库的基础上,通过对VB调用MATLAB数学函数库所涉及的几项关键技术———数组的存储方式、指针的应用和错误处理机制的统一等的研究和分析,并通过一个求解矩阵特征根和特征向量的具体实例,实现了增强VB数值计算能力的方法。结果表明:充分利用MATLAB的数学函数库,有助于开发出可以脱离MATLAB环境独立发布的VB的应用程序,在算法设计和缩短开发周期等方面有极大的应用价值。

According to the situation that VB is insufficient in numerical computation ability and is weak in algorithm development and program publish ing,based on introducing MATLAB C/C ++math function library and through analysing several key technologies:storage way of array,pointer application and unifying of error treatment ,which are referred in VB Calling MATLAB,and using a function used to solve matrix eigenvalue and eigenvector as a concrete sample,the method of intensifying numerical computation in VB is put into execution.The result indicate s that making use of MATLAB math function library is helpful to develop VB application program,which could be published without MATLAB,and is valuable on algorithm design and shortening developing period.
