基于小波方法实现降噪--语音增强--MATLAB(wavelet denoising---matlab)

说明：  进行数据的预处理，标准化和白化，便于数据的后续分析(Data preprocessing, standardization and whitening, facilitate the subsequent analysis of data)

说明：  这是实际加噪后的地震信号，可以直接采用用于实验的分析和处理(This is the actual noise after the seismic signal, can be used directly)

几个FDTD程序，对初学者很重要，很有参考价值。(Several FDTD procedure is very important for beginners, it is reference value.)

利用超声导波的形势，测量骨头的厚度，从而判断骨头是否患有骨质疏松症(ultrasonic guided wave measurement in bone)

以二体问题为模型，从地球发射航天器探索火星，途中需经过一次无动力金星借力，寻找最优（总速度增量最小）的发射时间窗口和飞行时间，并绘制地球到金星的Pork-Chop发射能量等高线图。发射时间窗口为2023—2033年，总飞行时间不得大于2年。(Taking the two body problem as the model to explore Mars from the earth, it is necessary to seek an unpowered Venus transit force on the way to find the optimal time window and time of flight (the minimum total velocity increment), and draw the contour map of the Pork-Chop emission energy of the earth to Venus. The total launch time window is from 2023 to 2033, and the total flight time is not more than 2 years.)
