说明：  多变量寻优的源码，包括基本算法如下：DFP法（又称变尺度法），BFS法、一阶梯度法，共扼梯度法。(multivariate optimization of the source code, including basic algorithm is as follows : DFP Act (also known as the variable scale), BFS, a ladder degrees, a total of the accused gradient method.)

图像检索与查询，实现图像的检索与查询，用matlab编程实现，其中含有图片。(image retrieval)

说明：  Matlab for VQ 向量量化編碼(Matlab for VQ vector quantization)

使用前请先将信号转换到时频域，最后将信号从时频域转换到时域(please transform the signal into time-frequency domain before using)

这里有三个music算法用于来波方向估计的算法，不同的表述，专门用来做对比用的(There are three music algorithm for DOA estimation algorithm, a different formulation, designed to make comparison with the)

对QPSK解调系统完美建模，其中通过改变码元速率和载波频率，再计算相应的环路滤波器的参数，即可实现多种QPSK模型的解调，且该模型可通过SYSTEM generator进行量化，从而生成ISE能直接使用的HDL代码。 matlab版本：2007a(Perfect for QPSK demodulation system modeling, which by changing the symbol rate and carrier frequency, and then calculate the corresponding parameters of the loop filter, QPSK demodulator can achieve a variety of models, and the model can be quantified by SYSTEM generator thereby generating ISE HDL code can be used directly. matlab version: 2007a)
