Hi, As I know, UmfPack is part of SuiteSparse [1]. I think you need to install that first. Best, KK [1]http://faculty.cse.tamu.edu/davis/suitesparse.html On Fri, Oct 30, 2015 at 2:50 PM, Joshua N Pritikin <jpritikin at pobox.com> wrote:
A recent post on the Eigen support forum suggests that UmfPack offers the best performing sparse LU decomposition, https://forum.kde.org/viewtopic.php?f=74&t=128919&sid=6498e59768f42c2393dda6c5a5228df4 I tried to include Eigen/UmfPackSupport, but I got /opt/R/x86_64-pc-linux-gnu-library/3.2/RcppEigen/include/Eigen/UmfPackSupport:9:21: fatal error: umfpack.h: No such file or directory Can somebody speculate on how much work is involved to get this to work?
