基于MATLAB函数库增强VB数值计算能力的研究

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。

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

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.
