三角波及其频谱三角波及其频谱三角波及其频谱(The triangle spread the spectrum)

自适应波束形成MATLAB算法编程，采用最小均方差优化准则(beam forming matlab codes)

说明：  SAR图像的滤波器，包括GAMMA、lee以及中值滤波(SAR image filters, including GAMMA, lee, and median filtering)

利用matlab产生FSK信号，里面有详细的说明，源代码注解。非常详细，非常经典。(very good )

将声音文件在时间轴上分割成几段，分别将段的秩序及某些段内的秩序颠倒，从而实现了对声音文件的加密。首先，先读取一个声音信号，对信号做1024点FFT变换，取完点之后，分成四个向量，四个向量组成一个矩阵，再对每一个向量进行转置，再重新整合，从而就实现了回密的过程。(Sound files on the timeline will be divided into paragraphs, each paragraph of the order and reversed the order of some paragraphs to realize the encryption of sound files. First, the first reading of a voice signal, the signal was 1024 points FFT transform, check after the completion point, divided into four vectors, the four vectors form a matrix, then for each vector transpose, re-integration, which will achieve a return to close the process.)

本代码为《精通matlab7》的配套代码，方便大家直接运行使用。(The code for the " proficient matlab7" supporting code, easy to use you to run directly.)

基于空间飞行器的姿态仿真源程序，仿真表明非常的准确。(Based on the spacecraft attitude simulation source code, simulation shows that very accurate.)

余弦分析采用最小二乘法，以适应一个正弦波的时间序列。余弦分析通常用于生物时间序列分析，演示predictible的节奏。这种方法可用于一个不平等的间隔时间序列。(Cosinor analysis uses the least squares method to fit a sine wave to a time series. Cosinor analysis is often used in the analysis of biologic time series that demonstrate predictible rhythms. This method can be used with an unequally spaced time series.)

MATLAB遗传算法OX变换的源代码(OX Transform MATLAB genetic algorithm source code)

说明：  初始对准，matlab程序，希望有用，对初学者有用，静基座对准(Initial alignment, matlab program, I hope useful, useful for beginners, static Alignment)
