I tried to modify the code,thanks for noticing...now i get that the function
cannot be evaluated at initial parameters.However I do not know what does
that mean..Should I try to modify parameters. I am still not sure of syntax

Hi,
Basically what I am trying is to rewrite matlab code into R ...This is code

Hi ,
can i ask if somebody know the syntax for optim function with multiple
variables:
I have function f (params,y,g,h,j) returnig z
y<-C(0.2,0.5,0.6)
where
params<-c(x1,x2)
I define g,h,j and then I define params, then use
optim to structure it ..ho
