Subject: Re: Problem with Newton Raphson Method for Two Variables

>Hello,>>    I have two functions, f1(x1)=a1*exp(b1*x1) >and f2(x2)=a2*exp(-((x2-b2)/c2)^2)>where a1, b1, a2, b2 and c2 are constants. x1 and x2 are dependent variables.>I need to solve the two functions using newton raphson's method. Can anyone help >me?>>Thanks>Shubha>>>>>>Except for trivial cases, both functions f1 and f2 don't have a zero.>>Moreover, f1 only depends on x1 and f2 only depends on x2.>>So what exactly are you trying to do with Newton-Raphson ?>>>>Best wishes>>Torsten.>>>>>>>>>Hello Torsten>>>>>>I'm trying to obtain the values for x1 and x2. Yes exactly, f1 only depends on x1 >>>and f2 on x2, while x1 and x2 are dependent on each other. Since the two >>>functions are non-linear, I use NR method to optimize until a certain tolerance limit.>>>>>>ShubhaHello Shubha,it's stiill not clear to me what you are trying to do.You write: "I'm trying to obtain the values for x1 and x2."What values ? What should these values satisfy ? Should they satisfy f1(x1)=0 and f2(x2)=0 ?You write: "x1 and x2 are dependent on each other."How ? Can you give the function how they depend on each other ?Best wishesTorsten.
