Hello,
We are occasionally getting matrix results that appear to be corrupted... here are the last several rows of an example. These are supposed to be floating point numbers.
[25015,] 1.820848e-01-3.2090e-06i
[25016,] 2.178046e-01-4.8140e-06i
[25017,] 1.820848e-01-3.2090e-06i
[25018,] 1.820848e-01-3.2090e-06i
[25019,] 1.144594e-01-1.6657e-06i
[25020,] 1.820848e-01-3.2090e-06i
[25021,] -1.293271e-01+4.3889e-06i
[25022,] 1.144594e-01-1.6657e-06i
[25023,] 1.820848e-01-3.2090e-06i
[25024,] 1.820848e-01-3.2090e-06i
[25025,] 1.173487e-01-4.4415e-07i
[25026,] 1.820848e-01-3.2090e-06i
[25027,] 1.375304e-01-3.6167e-06i
[25028,] 1.820848e-01-3.2090e-06i
[25029,] -1.293271e-01+4.3889e-06i
[25030,] 1.820848e-01-3.2090e-06i
[25031,] 1.820848e-01-3.2090e-06i
[25032,] 1.820848e-01-3.2090e-06i
[25033,] 1.820848e-01-3.2090e-06i
Any general idea what may be going on here?
It is a sporadic problem... it occurs maybe 2% or 3% of the time when running this particular script on various data.
I apologize for not including a pared-down example that reproduces the problem.... we are using an R script written elsewhere on large data sets. If someone wants more specifics please follow up.
