image comparison and degradation

说明：  频域的模态参数识别方法之一，可以对振动信号进行分析处理，得出结构的固有频率，阻尼比，振型系数，方法很好，程序完整，(Frequency-domain modal parameter identification methods that can analyze the vibration signal processing, draw the structure of natural frequencies, damping ratio, mode shape coefficient, very good method, program integrity,)

说明：  野人过河问题属于人工智能学科中的一个经典问题，问题描述如下： 有三个牧师（也有的翻译为传教士）和三个野人过河，只有一条能装下两个人的船，在河的任何一方或者船上，如果野人的人数大于牧师的人数，那么牧师就会有危险. 你能不能找出一种安全的渡河方法呢？的matlab程序！(Savage river belongs to the problem of artificial intelligence disciplines a classic problem, it is described as follows : There are three priests (also translated some of the missionaries) and the three Savage cross the river, only one can hold the next two boats in the river or any of the parties on board, if Savage is greater than the number of priests the number of priests will be so dangerous. you can find a safe way to cross the river? The Matlab procedures!)

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))

programs in matlab designing

在MATLAB/simulink下，搭建三相四线制非线性负载。(In the MATLAB/simulink, the three-phase four-wire system to build non-linear load.)

The code implements an approximation of the multivariate bandwidth calculation from (The code implements an approximation of the multivariate bandwidth calculation from [1]. In contrast to other multivariate bandwidth estimators, it can be estimated from a preclustered sample distribution offering a simple way of estimating compact and accurate KDEs with variable kernels.)

对普通 RJMCMC算法提出了改进算法，并由MATLAB实现。(Ordinary RJMCMC algorithm proposed an improved algorithm, MATLAB realization by.)

扫地机器人的一种路径规划算法，内螺旋法，首先构建了房间地图，然后遍历了房间。(A path planning algorithm sweeping robot, spiral method, first built room map, then traverse the room.)
