matlab的时频分析源代码，针对小波分析和其他的时频方法，希望对大家有帮助！(time-frequency analysis matlab source code for wavelet analysis, and other time-frequency methods, we want to help!)

数字版权保护的毕业设计，利用DCT进行变换，但是算法比较新颖，里面包括所有的matlab程序。(digital copyright protection graduation design, for the use of DCT transformation, but rather novel algorithm, includes all the Matlab procedures.)

methode de guss par matlab commande

leap frog algorithm for solving metaheuristic problems and shortening the path to find the most optimized path.

说明：  无约束一维极值问题中的抛物线和三次插值法，例程可调(Unconstrained extremal problem in one-dimensional parabolic and cubic interpolation method, routine adjustable)

it is the program for rls algorithm for a sound wave

各种形式的方向图，波束形成中有常规波速形成，等等(Various forms of pattern, with a conventional beamforming beamforming, etc.)

用matlab实现的基于LSB的数字水印算法。算法可以在BMP灰度图像中嵌入水印，水印信息为二值图像，并将其扩展到与原始图像同样大小，进行重复嵌入，提高鲁棒性。同时算法中给出了PSNR值以评价水印图像的效果，(Using matlab realize the number of LSB-based watermarking algorithm. Algorithm can be embedded BMP gray image watermark, watermark information for the binary image, and its expansion to the original image the same size, the repetition of embedding, improve robustness. At the same time algorithm PSNR values are given to evaluate the effect of watermark images,)
