工程振动中的数值方法 西北工业大学 课件(Numerical methods in engineering vibration Northwestern Polytechnical University Courseware)

经典Dijkstra算法的matlab实现(Dijkstra algorithm based in matlab)

基于改进的SLM算法来估计波达方向DOA，给出了仿真模型、结果及分析。(SLM based on an improved algorithm to estimate DOA DOA, the simulation model, results and analysis.)

这段程序是产生一个叠加信号，然后计算传递函数，进行相关分析(this is a program which generate a new signal,calculate transfer function and doing correlation analysis )

this code useful for padding zeros in ofdm.it is the function used in ofdm_ber file.

说明：  五点三次平滑法可用作时域和频域信号平滑处理。对时域作用是减少混入振动信号中的高频随机噪声。对频域是能使谱曲线光滑。(Three five-point smoothing method can be used as time domain and frequency domain signal smoothing. Effect on the time domain vibration signals to reduce high-frequency mixed with random noise. On the frequency domain is the spectral curve can smooth.)

说明：  辨识信号的幅值、相位、频率；参数估计；低频振荡(Identification of the amplitude, phase, frequency of the signal; parameter estimation; low frequency oscillation)

计算机视觉的经典教材，最权威的著作，此领域必备(a classic book on computer vision, which is very famous and a must in this area)

这是用汉语注释的EMD程序，很不错的。％ 语法 ％ IMF = EMD(X) ％ IMF = EMD(X,..., Option_name ,Option_value,...) ％ IMF = EMD(X,OPTS) ％ [IMF,ORT,NB_ITERATIONS] = EMD(...)(This is annotated in Chinese EMD procedures, very good. Syntax IMF = EMD (X) IMF = EMD (X ,..., Option_name, Option_value ,...) IMF = EMD (X, OPTS) [IMF, ORT, NB_ITERATIONS] = EMD (.. .))

8 band kp method calculate the valence band structure, using finite difference method
