改进遗传算算发，MATLAB，收敛快，精度高，效果不错，适用于近似求解和NP难问题(Genetic calculate fat, MATLAB, convergence, high precision, good results for NP hard problem to solve and approximate)

Script originally intended for use in oceanography/fluid dynamics. Use: >> ipdv(X,Y) (0,0) default initial position or >> ipdv(X,Y,Xo,Yo) (Xo,Yo) initial position 2D vector components (X,Y) are used to plot the vectors one after another, i.e., next vector starting at the end of the previous one (via Matlab s quiver.m ). This function handles NANs (Not-A-Number) by putting Zeros in their place, thus allowing the Matlab cumsum.m function to compute the progressive positions (Matlab function cumsum.m doesn t skip Nans). NaNs produce discontinuities in the graphic.

绘制电容电压变化曲线 电阻、电感、电容串联电路R、L、C，试求电路突然接通电源E时，电源电压uc(t)的变化规律，并绘制R=1,L=0.5,C=1,E=1,uc（0）=0，uc’（0）=0时的电容电压uc(t)d 的变化曲线。 (Draw capacitance voltage variation curve resistor, inductor, capacitor series circuit of the R, L, and C, Find circuit suddenly turned on the power supply E, the variation of the supply voltage uc (t), and draw the R = 1, L = 0.5, C = 1, E = 1, UC (0) = 0, uc ' (0) = 0 when the capacitor voltage uc (t) is the change of d curve.)

这6个程序可用于0—9的数字识别，算法包括：基于类中心的欧式距离法、马氏距离法、夹角余弦距离法 、二值化的夹角余弦距离法、二值化的Tanimoto测度法和增量校正算法，均为基于matlab软件编写的程序。学会了这几个算法，可以在这些程序的基础上进行扩展，对三维模型识别算法的编程有一定的帮助。(6 program can be used 0-9 digit recognition, algorithms include: class center Euclidean distance, Mahalanobis distance method, the cosine of the angle distance method, the cosine of the angle distance method binarization, binary of Tanimoto Measure Method and incremental correction algorithms are written based on matlab software program. Learned these algorithms can be extended on the basis of these procedures, programming algorithm of the three-dimensional model to identify some help.)

地球物理勘探中重力资料解释的主要目的是由地表观测值推断地下可能存在的密度分布。众所周知,任何一组重力数据都可能由无数个密度分布所引起。即使假设了重力异常是由具有均匀密度差的单一地质体产生的,也得不出唯一的解(Gravity geophysical exploration data interpretation main purpose is inferred from surface observations may exist underground density distribution. Is known, any set of data may be provided by gravity density caused numerous. Even assuming that the gravity anomaly is determined by having a uniform density difference arising from a single geological body, they have no unique solution)
