rmfgen (rmfgen-2.8.7) [xmmsas_20230412_1735-21.0.0]

Variable length column support

rmfgen writes out RMF matrices in variable-length vector column format. This results in smaller matrices than the alternative fixed length format and reduces the demands on machine resources. The default thresholding used is such that elements less than $1.0\times10^{-6}$ are ignored by default.
