Dear useRs,
This post relates to a similar problem (
https://stat.ethz.ch/pipermail/r-help/2010-August/250719.html)
I am using R.matlab (R.matlab v1.6.3 (2013-01-17) to iterate matrix
multiplication in matlab 2012Rb. Everything works fine except for some
random iteration of my model the command getVariable would fail to bring
matlab objects back to R. Could someone help me understand what's going on
behind the scenes ?
Here is the command lines I use th launch the matlab server
library(R.matlab)
Matlab$startServer()
Sys.sleep(10)
matlab <- Matlab(host="localhost")
if (!open(matlab))
throw("Matlab server is not running: waited 30 seconds.")
setVerbose(matlab, -2)
Here is the eval expression used followed by the error displayed in the
matlab command window.
