FIR-filter

实现matlab仿真生成ofdm系统，但不涉及信道估计等内容(Matlab simulation ofdm achieve generation systems, but does not involve channel estimation, etc.)

本人修改过的elm的matlab算法，该算法比原来的elm的算法在超过3个神经元后的计算速度能明显加快！原理是运用函数产生列矩阵！！ ELM 是一种快速的神经网络算法，本人已经比较过，比很多流行的算法（BP,SVM）都快,而且效果很好，运行环境是matlab，可以测试所有的benchmark的数据(I modified elm of matlab algorithm elm than the original algorithm in more than three neurons after the computing speed can significantly speed up! The principle is to use functions to generate the matrix out! ! ELM is a fast neural network algorithm, I have a comparison, than many popular algorithms (BP, SVM) faster, and the effect of good operating environment is matlab, you can test all of the benchmark data)

说明：  matlab的经典实用100例，是在做仿真的好帮手(matlab classic 100 cases of utility is a good helper to do simulation)

Single phase full bridge rectifier circuit

测量激光散斑图的统计尺寸，给出散斑二阶统计量的值(speckle size)

说明：  用牛顿下山法求解方程：下山因子在计算过程中可以变动，一般选择下山因子时从1开始，逐次将减半进行试算，直到能使下降条件成立为止。若当计算到某步时取不到满足要求的值（或值小到无法容忍），这时称“下山失败”，需要另取初值重新算起。(Descent method with Newton' s equation: down factor in the calculation process can change, usually selected from the 1 start down factor, will be halved for successive spreadsheet until the can down the conditions established. If when calculating the time to take a step not meet the requirements of the value (or values ??too small to tolerate), then the &quot down failed&quot , you need an alternative initial re-counting.)

说明：  基于AR模型，通过已有的70个随机数进行的预测。用matlab实现。(AR-based model, the random number 70 has been carried out predictions. Using matlab implementation.)

摄像机标定的matlab算法，用于快速标定摄相机。(camera calibration algorithm in Matlab, for rapid calibration camera.)
