| Apr 20, 2014 at 12:09 | comment | added | Hack_man | I am using R and I have a data set like > data_ref x y r 1 -1.90 -0.70 2.04 2 -0.90 -0.50 0.90 3 0.63 -0.65 0.72 4 0.31 -0.01 0.30 5 0.04 1.25 1.20 where x,y are the location of any antena, r is the distance of a device from there antenna. I am trying to minimize the residual as follows function(x,y,x0,y0,r) (sqrt(sum((x-x0)^2+(y-y0)^2))-r[1]+sqrt(sum((x-x0)^2+(y-y0)^2))-r) nlm(norm_vec,c(mean(data_ref$x),mean(data_ref$y)),x0=data_ref$x,y0=data_ref$y,r=data_ref$r) where x0, y0 is the seed point for iteration. but its not working, Can someone help me in understanding the flaw in my concept?
