OFDM经典注水算法，可以直接调用，有参考价值(OFDM water classic algorithms, can be called directly, there is reference value)

图像分析和识别中一个关键的内容就是图像参数的量测，本程序可实现一些参数的量测。( In the image analysis and the recognition an essential content is the picture parameter 閲忔祴, this procedure may realize some parameters 閲忔祴. )

此程序实现了对地震检波器的模态分析，有利于我们更加深入的了解作为地震信号采集前端的检波器的特性。(This program realizes the geophone modal analysis will help us more in-depth understanding of a seismic signal acquisition front-end detector characteristics.)

沿著軌道運動的紅點，画一个红点让其沿着所画图形开始运动(Along the orbital motion of the red dot)

％File: c9_estimatepi.m ％有5个pi的估计，每一个都是基于500次重复随机试验，所得的pi的五个估计值用以下向量表示 ％pi的估计值=[3.0960 3.0720 2.9920 3.1600 3.0480] ％如果对5个结果进平均，则pi的估计值=3.0736,这样的结果等价于2500次的试验结果。( File: c9_estimatepi.m have 5 pi estimates are based on a randomized trial to repeat 500 times the income of the five estimated value of pi with the following vector, said the estimated value of pi = [3.0960 3.0720 2.9920 3.1600 3.0480] if the results into an average of 5, then the estimated value of pi = 3.0736, so the result is equivalent to 2500 times the test results.)
