[Rcpp-devel] Issue on eig_sym()

[Tiago Fragoso]

Hello all,.

I am running into the following issue on eig_sym() when using RcppArmadillo:

error: eig_sym(): failed to converge


error: matrix multiplication: incompatible matrix dimensions: 0x0 and 108x1

It occurs somewhat at random (this time, I had the surprise around
iteration 10^6), mostly when I use "dc" as an argument for eig_sym and/or
when the matrix being decomposed is big (order >100). This is also a new
issue. I never had this issue (using the same code) before this past two
months.

Any thoughts?

Best Regards,

Tiago
