这是一个matlab图像处理函数汇总，本人感觉很好，到时可以查就了然于心(This is a summary of matlab image processing function, I feel good, to the clear understanding can check on the heart)

this algoritm is writen for some adaptive algoritms such lms and vlms algoritm o achive the adaptives and noise canslations

说明：  function for texture classsification

QAM 正交频率调制，调制及解调全部代码，由MATLAB实现整个通信系统。(QAM orthogonal frequency modulation, modulation and demodulation of all the code from MATLAB entire communication system.)

C语言编写的傅立叶正逆变换，经过测试与matlab里面的.m算法结果一致。还有数据测试可用。适用于工程信号处理中。(C language of the Fourier transform, After test and Matlab inside m algorithm results. There are data test available. Suitable for engineering signal processing.)

OFDM信号的频偏校正程序，用于估计子带上的频率偏移。(OFDM signals in frequency offset correction procedure used to estimate the sub-band frequency deviation.)

matlab 自适应有限元方法，主要为二维椭圆型方程(Adaptive finite element method for two-dimensional elliptic equations)

parsing header values into elements.

matlab 模拟退火经典程序，简单但实用，能很好的理解模拟退，里面还有一个无约束优化的例子(matlab classical simulated annealing procedure, a simple but practical, a good understanding of simulation can retire, which have an example of unconstrained optimization)

MIMO雷达模型下一种子空间谱估计方法，采用过估计的方法，以避免信源数估计的问题，直接对数据协方差矩阵进行变换，从而构造了信号子空间投影矩阵和噪声子空间投影矩阵，不需要像经典的MUSIC一样对其进行特征分解，完全避开了在一般非理想情况下MUSIC算法必须面对的识别小特征值与大特征值的麻烦，降低了复杂度，而且该方法不受快拍数的影响，在相干源情况下也能准确的估计目标的入射角，不会出现伪峰。(A subspace based DOA (Direction-Of-Arrival) estimation method for MIMO (Multiple-Input Multiple-Output) radar is studied in this paper. By transforming the data covariance matrix, we can construct the projection matrix of signal subspace and noise subspace. The computation complexity of the algorithm is reduced as it does not need to perform eigendecomposition. By using the over estimated theory, this algorithm avoid estimating the number of signal sources and can keep a good estimate performance in the case of lower SNR (Signal-to-Noise Ratios) and multi-target. )
