利用matlab编写的基于计算机声卡的虚拟仪器，含信号发生器、示波器和频率计，并利用matlab中guide可视化编程实现了界面操作。-Matlab prepared using computer sound card based virtual instrument, with the signal generator, oscilloscope and frequency meter, and use visual guide matlab programming in the interf

使用VC ++程序生成任意分布的随机数，类似示波器的演示代码，基于几何直观面积的方法，以正态分布随机数的产生为例讨论了任意分布的随机数的产生方法，界面做的不错-VC++ program using any random number generation, similar to the scope of the demonstration code, based on the visual area of ​ ​ the geometric approach to norma
