numerical computing with the help of matlab

使用MATLAB实现卷积码的编译码，信源为随机产生数，进行软判决译码(Convolutional code using the MATLAB implementation of the codec, source for the randomly generated number, to soft-decision decoding)

说明：  基于小波变换模极大的多尺度图像边缘检测matlab源代码，该算法采用的是样条小波，为了更好的检测边缘，用多孔算法代替了mallat算法。该算法和mallat快速算法主要区别： 1 多孔算法不需要抽取偶数样本，所以奇异检测定位更准确，相应的重构是不需要插零。2 多孔算法需要对滤波器进行伸缩。(based on wavelet transform modulus maxima of multiscale edge detection Matlab source code, The algorithm used is kind of wavelet, in order to better detect the edge of porous algorithm instead of Mallat algorithm. The algorithm and fast algorithm Mallat major difference : an algorithm porous not even take samples So singular position detection more accurate, the corresponding Reconstruction interpolation is not zero. Two porous algorithm need to filter extendable.)

This code is Cuthill-Mckee bandwidth Reduction(CMBR) algorithm.This scheme is used in FEM to minimize the size of assembled stiffness and mass matrix.

说明：  matlab振动试验数据分析，信号获取：测量获取设备的信号（振动、转速、过程参等）。信号分析：从信号中提取反映设备运行状态和故障的特征值。故障诊断：根据信号特征信息，对故障进行诊断（专家诊断、智能自动诊断）和预测(Matlab vibration test data analysis, signal acquisition: Measurement and acquisition of equipment signals (vibration, speed, process parameters, etc.). Signal analysis: extract the characteristic value of equipment running state and fault from the signal. Fault diagnosis: fault diagnosis (expert diagnosis, intelligent automatic diagnosis) and prediction according to signal characteristic information)
