OFDM

这个函数用于估算光谱中的最大信息熵，它同时满足了倒频谱的局限和相关谱的局限(This function provides an ARMA spectral estimate which is maximum entropy satisfying correlation constraint (number of poles)and cepstrum constrains (number of ceros))

some notes abou svd in matlab functions

modified newton raphson的源程序，可以实现非线性elastic求解F或是displacement(modified newton raphsom)

对利用录音设备对手机、电话等按键式密码输入终端进录音盗取银行卡密码的不法行为进行技术分析，利用MATLAB软件编程对按键式密码输入终端的按键音进行音频分析，基于短时能量和过零率对所采集的音频文件进行端点检测，提取出单个拨号音，然后对处理后的音频进行频谱分析、对比，从而识别按键式密码输入终端的按键音。(On the use of recording equipment on the phone, telephone touchtone input terminal password into the recording steal bank card passwords wrongful conduct technical analysis using MATLAB software programming for touch-tone touchtone password input terminal for audio analysis, based on short-term energy and zero-crossing rate of the acquired endpoint detection audio files, extract single dial tone, and then processed audio spectrum analysis, comparison, to identify key tone touchtone password input terminal.)

计算高程，可以计算高程的平差值，误差，中误差，等等东西，非常方便使用，数据易于导入(The Height)

循 环 相 关 谱检 测 法 的 检 测性 能 优 于循环 相 关 谱 系 数 检 测法,但 循环 相 关 谱检 测法 的 性 能 受 噪 声 功 率 估 计 误 差 影 响 大,而 循环 相 关 谱 系 数 检 测 法 不 需 要 已 知 噪 声 功 率,实 用性 更 强(Circular correlation spectrum inspection measurement method of inspection measurement can be optimal in cyclic correlation spectrum coefficient measuring method, but closed loop phase spectrum detection method of measuring performance is affected by the noise power estimation error is large, and cyclic correlation spectrum coefficient test don t need to noise power ratio is known, use sex is stronger)

自编的增加维数精细积分求解非线性动力学方程的程序(pim method)

此程序实现了一种自适应算法，并详细分析了其实现过程(This procedure has realized one auto-adapted algorithm, and multianalysis its realization process )
