Simple mouse control using motion detection with matlab. It s not perfect, just an outline, needs improvements.

MATLAB Codes for Calculate the line of sight Channel Gain

当水下存在多个目标时，利用平均声强器检测已经不再有效，此时使用复平均声强器来确定多目标的方位。(When existing multi sources, average acoustic intensity does work. At this case, complex average acoustic intensity can obtain the direction of multi sources.)

说明：  HHT算法实现emd分解，及希尔伯特黄变换，实现瞬时频率瞬时幅值，边际谱的提取(Perform modal recognition, Hilbert Huang transform and its associated algorithmic program code for signal analysis and processing)

matlab对语音信号滤波，并比较滤波前后的音效。(matlab on the voice signal filtering, and compare the sound before and after filtering.)

分析了该信号的时域、频域、倒谱，循环谱等,基于kaiser窗的双谱线插值FFT谐波分析，可以得到很精确的幅值、频率、相位估计。( Analysis of the signal time domain, frequency domain, cepstrum, cyclic spectrum, etc. Dual-line interpolation FFT harmonic analysis kaiser windows, You can get a very accurate amplitude, frequency, phase estimation.)

matlab的实验报告，有雅可比迭代，最小二乘法和复化辛普森公式。(matlab experimental reports, Jacobi iteration, the least square method and complex formula of Simpson.)

matlab6.5的源代码，包含了所有实例的源代码，请多多支持！！(matlab6.5 source code, contains all instances of the source code, a lot of support! !)

定温边界条件下，二维矩形平板的温度场差分数值模拟。(Constant temperature boundary conditions, two-dimensional rectangular plate differential temperature field numerical simulation.)

说明：  amplitude modulation
