采样定理 用来对模拟信号进行采样 使其变成数字信号 观察其频谱(Sampling theorem is used to carry out sampling of analog signals into digital signals so that it observe the spectrum)

用“提前停止”方法提高BP网络推广能力 本例将用提前停止和训练函数TRAINGDX相结合来避免“过度拟合”产生的误差 (The " early stopping" method to enhance the promotion of BP network capacity will be used in this case in advance and training function to stop the combination of TRAINGDX to avoid " over-fitting" error)

预测交通客流量，通过前20年的公交数据，预测今后5年的公交客运量。(Forecast traffic traffic through the first 20 years of public transit data, to predict the next five years passenger transport.)

matlab编程计算结构系统的频率响应程序(matlab program to calculate the frequency response of structural systems)

经典的信息论准则估计信号源个数。 使用空间谱估计理论，模拟发射信号由天线阵列接受采样。经过AIC和MDL两种算法，估计出采样序列中信号的个数，所加噪声是白噪声。(Classical information theory for sources number estimation. It s spatial spectrum estimation theory. it analogs transmission signal from the antenna array . It uses two algorithms“ AIC and MDL ”to estimate the number of sampled signal sequence. the added noise is white noise.)
