Calculates a time-window based cross-correlation for two real input vectors.

设有连续时间周期信号，它的周期为T，角频率，且满足狄里赫利条件，则该周期信号可以展开成傅里叶级数，即可表示为一系列不同频率的正弦或复指数信号之和。(With continuous time periodic signal, its period is T, the angular frequency, and to meet the Diliheli conditions, the periodic signal can be expanded into a Fourier series, can be expressed as a range of different frequencies of sinusoidal or complex exponential signal and.)

真空中二维FDTD程序，利用了二阶边界条件，具有比较好的学习参考价值(2D FDTD program )

神经源PID控制源码，。M文件，是以进行PID控制时的必备文件，可以参考一下(PID control of neuronal source. M files, based on the PID control of the required documents for reference)

说明：  卡尔曼滤波，分别用UKF、EKF用于非线性飞行器系统，飞行器模型分别采用CA/CV/Jerk/sin模型(Kalman filter, UKF, EKF for nonlinear aircraft systems, respectively, aircraft model using CA / CV / Jerk / sin model)

利用STDM方法嵌入水印信息，可设置量化步长，选择各种经典的攻击方式，控制攻击强弱，返回误码率和峰值信噪比(Stdm method using embedded watermark information, to set the quantization step size, choose a variety of classic attacks, controlling the strength of the attack and returned to the bit error rate and peak signal to noise ratio)
