介绍了一种基于VB 后台调用ANSYS和MATLAB进行设计计算的方法。通过借助VB设计的参数化输入界面， 调用APDL编写的模型分析程序和MATLAB编写的可靠性计算程序，实现了在用户界面上以可视化的形式显示计算结果功 能，并应用于铁路接触网设计的可靠性计算中，结果显示证明了计算软件的可行性和实用性。(Describes the background of a call based on ANSYS and MATLAB VB design calculation. VB by using the design parameters of input interface, called APDL model prepared by the procedures and the reliability of computer program written in MATLAB, implementation in the user interface to visualize the results in the form of display features, and design used in railway catenary the reliability of the calculation, the results proved the feasibility and practicality of computing software.)

说明：  产生一个10000位的bipolar信号并画出bit error performance的模拟图像，求出BER(The source generates equally probable bits, P(0) = P(1) = 0.5. (a) Construct a program to generate 10000 bits with bipolar signaling. (b) Use your program to simulate the bit error performance of the system with Eb/N0 = 0, 2, 4, 6, 8, 10 dB. (c) Compare your simulated performance with the analytical expression for the bit error rate (BER):)

Taup域的反射法正演MATLAB程序，还不错，希望大家下去看看！(Taup domain reflectometry forward MATLAB program, well, I hope you go to see!)

有一个长直金属接地板，侧壁与地面电位为0，用有限差分求槽内电位分布(A long straight up, wall and floor of metal surface potential for 0, with finite difference for slot potential distribution)

基于MATLAB的QPSK通信系统仿真源码，信道误码率等(MATLAB-based simulation of communication systems QPSK source, channel bit error rate)

Matlab被称为第四代计算机语言，利用其丰富的函数资源，可使编程人员从繁琐的代码中解脱出来。Matlab用更直观、符合人们思维习惯的代码，代替了C和Fortran语言的冗长代码，给用户带来的是最直观、最简介的程序开发环境。(Matlab is called fourth-generation computer language function, programmers can be freed from the tedious code. Matlab with a more intuitive, the code in line with people' s habits of mind, instead of a lengthy code in C and Fortran languages, giving users the most intuitive and Introduction program development environment.)
