适合神经网络初学者.程序中已经输入实验数据,在matlab环境下直接运行即可.可以输入其它新数据,并改动.(neural network for beginners. Procedures have been imported experimental data, in Matlab environment can be run directly. the importation of other new data and changes.)

《Matlab在化学工程中的应用》该书是我见过的一本相当有用的一本书 具有很高的针对型哦("Matlab in chemical engineering application," I have seen the book is of a very useful book is a against high-Oh)

计算hurst指数 主程序 利用经典的RS分析法计算分形H指数(calculate hurst parameter)

Step 1: Set i=1 FA=f(a) Step 2: while i≤ No do step 3-6. Step 3 set p=(a+b)/2 FP=f(p) Step 4 if FP<TOL or (b-a)/2<TOL then OUTPUT(p) STOP. prepared by Razana Alwee 24 Algorithm Step 5 set i=i+1 Step 6 if FA.FP > 0 then set a=p FA=FP else set b=p. Step 7 OUTPUT (‘Method failed after No iteration, No=’, No)
