说明：  多元微分方程参数识别，对网友的问题进行编程，并求出了准确结果，使用最小二乘lsqcurvefit函数 (multiple variable differentical equtation parameter estimation using matlab lsqcurvefit function,the reslut is good)((multiple variable differentical equtation parameter estimation using matlab lsqcurvefit function,the reslut is good))

说明：  用有限元差分发求解一维热传导，并作做出二维图线和三维温度变化图像(One dimensional heat conduction is solved by finite element difference distribution and plotted)

Hi , Here is a list of the files contained in RLS.zip FIR_RLS : FIR RLS demo (FIR is used when there is an access to the output i.e feedback is used like in a dc motor we use speed as feedback) IIR_RLS : IIR RLS demo (IIR is used when there is no access to the output the system model is only a function of the input i.e channel equalization prolbem ) FIRsampledata : a sample data for FIR RLS demo IIRsampledata : a sample data for IIR RLS demo Enjoy !
