做的一个关于水网解算的小程序，用的是把非线性方程转化为线性方程的思想去解决的，(Does a solver on the water network of small procedures, using the nonlinear equations into linear equations to solve ideological and)

QUIVERS(x,y,u,v,Gscale,Spos,Sunit) plots velocity vectors as arrows with components (u,v) at the points (x,y). The matrices X,Y,U,V must all be the same size and contain corresponding position and velocity components (X and Y can also be vectors to specify a uniform grid).

基于MIT律的MRAC,根据MIT自适应律编写的模型参考自适应程序，适用于初学者对自适应控制的理解与应用(MIT-based law MRAC)

HISTNORM Histogram normalized [...] = HISTNORM(...) works like HIST, but the frequency is normalized so that area sum is 1. Bonus usage! [...] = HISTNORM(..., plot ) plots and returns the output arguments. Be sure plot is the last argument. Example: data = randn (10000, 1) [xo,no] = histnorm(data, 101, plot ) hold on plot (no, normpdf(no), r ) hold off See also: HIST.
