DCT图像压缩算法。1.图象进行归一化 2.显示系数图象 3.重构及显示图象 4.显示误差图象 5.计算归一化图象的均方误差 (DCT image compression algorithm. 1. Images were normalized 2. Shows coefficient image 3. Reconstruction and display of images 4. Show the error images 5. Calculated normalized mean square error of image)

等间距线性阵列，阵元间距d= λ /2，等幅加权，目标方位φr = 0°，无噪声。 分别仿真计算阵元数M=8 、16时的阵列方向图，定性分析产生的原因。（可通过3dB波束宽度计算公式说明） (Equally spaced linear array, the array element spacing d = λ/2, equal amplitude weighted target azimuth φr = 0, no noise. , Respectively, the number of array elements M = 8 and 16 when the array pattern, qualitative analysis to produce simulation. (Available by 3dB beamwidth formula noted))

大地电磁最小二乘光滑约束反演，包含bostick反演对比(Smooth constrained least squares inversion of magnetotelluric, including bostick contrast inversion)

用FDTD法模拟无源区域二维TE波的传播，并加有一阶Mur吸收边界条件(FDTD method using two-dimensional simulation of passive TE wave propagation in the region, and add a first-order Mur absorbing boundary conditions)

fft算法的具体实现，应用基2法实现，有比较好的实验结果。(fft concrete realization of the algorithm, the application base 2 method achieved a relatively good results.)

说明：  基于核函数的偏最小二乘算法，先对原矩阵进行核函数非线性变化，再用非线性迭代求解(Kernel-based partial least-squares algorithm, first the original non-linear function of changes in the nuclear matrix, and then non-linear iterative solution)

Prony的matlab工具箱，很详细，使用它可以对信号进行prony变换和分析。(Prony matlab toolbox,the signal can be prony transformation and analysis.)

说明：  里面介绍的是使用禁忌搜索求解vrp，只要修改下数据就可以使用，用的是MATLAB写的(vrp MATLAB ts)

Calculate the histogram and the entropy of any image. The entropy is calculated using different methods.

一个PSO算法,matlab环境上实现，与大家交流(a PSO algorithm, achieving Matlab environment, and the exchange)
