基于PCA的人脸识别的Matlab程序，详细代码，简单易懂(PCA-based face recognition Matlab procedures, detailed code, simple and easy to understand)

nonlinear FEM analysis of 1 dimension bar

该代码仅计算了一个101×101尺寸的Gabor函数变换，得到均值和方差。代码采用两种卷积计算方式，从结果中可以看出，快速傅立叶变换卷积的效率是离散二维叠加和卷积的近50倍。 (The code is only the calculation of a 101 × 101 size Gabor function transformation, the mean and variance. Convolutional code using two methods of calculation can be seen from the results, fast Fourier transform convolution efficiency are two-dimensional discrete convolution superposition and nearly 50 times.)

说明：  基于MATLAB的高压直流输电仿真模型，模型包含整流和逆变两个部分。仿真模型运行结果成功，波形良好。(Based on MATLAB, the HVDC transmission simulation model consists of two parts: rectification and inverter. The simulation model runs successfully and the waveform is good.)

说明：  this module gives a basic image compression example

调制宽带转换器 matlab代码 实现频谱欠Nyquist速率采样检测(MWC Modulated Wideband Converser)

此算法先把伤病人员进行特殊对待，在计算出其他人的入院日期，表二的出院日期为 统计的期望值 运用是要改变 数据的初值 和u值（数据录入个数）；(This algorithm first special treat the sick and wounded, in the calculation of other people' s admission date, discharge date in Table II used for the statistical expectation is to change the initial data and u values ​ ​ (the number of data entry) )

用来计算地球表面两点之间的距离，该程序通过输入两点的经纬度坐标确定两点的距离，可用于各种工程应用当中(The Earth s surface used to calculate the distance between two points, two points in the program by entering the latitude and longitude coordinates to determine the distance between two points can be used in a variety of engineering applications which)

无约束优化的matlab程序。很全面，适用于数学建模等竞赛活动。(Unconstrained optimization matlab program. Very comprehensive, suitable for mathematical modeling contest.)
