I am using optim() to minimize a function of 19 variables and I repeatably get the following error
message:
R> source("/users/sat/rksh/goldstein/emulator/optimizer.R") sann objective function values initial value 5044.955275 Error in La.svd(x, nu, nv, method) : error code 1 from Lapack routine dgesdd R>
This error occurs whether I use SANN or Nelder-Mead. My objective function doesn't seem
to do anything odd near my starting value.
Does anyone have any experience of this error message?
