matlab程序设计教程，里面有源代码和PPT是一个相当不错的书，内容丰富，言简意赅适合大家学习和参考。(matlab programming tutorials, source code and PPT which is a very good book, rich in content, concise and comprehensive study and reference for everyone.)

利用周期图法对序列的功率谱进行估计。数据窗采用汉明窗。假设在白噪声中分辨这三个不同频率的正弦信号,其相位是均匀分布在2PI的独立随机变量,而 是一个单位白噪声.生成50个长度为N=512的 的样本序列集合。 (use map cycle sequencing method of the power spectrum estimation. Data window using Hamming window. Assume that the white noise to differentiate between the three different frequency sinusoidal signal, its phase is uniformly distributed in the PI two independent random variables. but a flat white noise. Generating 50 length N = 512 samples of the sequence set.)

用于求解不可压ns方程的动量守恒计算方程，采用了二维对称调用的技术。(Ns for solving equations of incompressible equation of momentum conservation calculation, using the technique called two-dimensional symmetry.)
