Dear All If you could please help me with a solution on the following: we have: a <-matrix(c(1,2,3,4,5)) x <-matrix(c(0.3,0.2,0.1,0.08,0.05)) b <-50*exp(-x[1]*a[1]) d <-b*exp(-x[2]*a[2]) e <-d*exp(-x[3]*a[3]) f <-e*exp(-x[4]*a[4]) g <-f*exp(-x[5]*a[5]) I would like to be able to calculate g with fewer steps, thought perhaps a function could do that? I apreciate your help, thanks Andras [[alternative HTML version deleted]]
