很好用的matlab wavelet,,,,,,,,,,(Good use of the matlab wavelet ,,,,,,,,,,)

一本介绍matlab GUI编程的书，里面包括了各种控件的编程，比如菜单、编辑框、按钮、列表框等。(An introduction matlab GUI programming books, which include a variety of control programming, such as menus, edit boxes, buttons, list boxes and so on.)

说明：  无区间约束powell算法MATLAB实现(No interval constraint algorithm for MATLAB implementation powell)

基于经验模态分解的管道超声回波信号噪声消除，是种比较好的方法(Elimination of the ultrasonic echo signal to noise based on empirical mode decomposition pipeline is a good method)

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.)

基于NSF算法的空间谱估计，获取目标方位(Spatial spectrum estimation, based on the NSF algorithm for target bearing)

说明：  matlab使用BP网络的例子,使用Levenberg Marquardt算法提高训练速度,效果不错(use Matlab BP example, the use of Levenberg Marquardt algorithm to improve training speed, good results)

基于pde的图片去噪算法，用于去除图片白噪声(Pde-based image denoising algorithm, white noise is used to remove pictures)
