MyWhiteNoise产生一个指定幅值范围的白噪声信号.(whiteNoise)

说明：  数字信号处理C语言集，IIR，FIR等以C语言实现，包含代码，及汇编过程(Digital Signal Processing C language set, IIR, FIR, etc. in C language, contains the code, and the compilation process)

合成孔径雷达仿真源代码，包括chirp信号、回波仿真、脉冲压缩、距离徙动、距离多普勒算法等五个源代码，是学习SAR仿真很系统的资料。(Synthetic aperture radar simulation source code, including the chirp signal echo simulation, pulse compression, range migration from Doppler algorithm source code, learning SAR simulation system.)

zemax与matlab调用程序，当您用matlab分析复杂数据时，可以利用zemax光路计算工具提供原始数据，由matlab分析，并且可以驱动zemax优化，对自由曲面的优化更为重要，此代码为matlab调用zemax的函数库。(ZEMAX and Matlab : A Powerful Pair ZEMAX features a built-in DDE (Dynamic Data Exchange) server that allows other Windows® applications access to ZEMAX functions. Programming DDE applications can be somewhat complex if you are working in a compiled language such as C++. An alternative is to use one of the scripting languages such as Tcl, Python or Matlab. Matlab is a great choice since it is much more than a scripting language. Matlab provides a wealth of functions for processing and visualizing scientific and engineering data and there are toolboxes for Matlab that extend the basic capabilities into a wide variety of more specialized areas and disciplines. )
