NAME
svdpackout.pl Reconstruct matrix from singular values output by SVDPACKC
SYNOPSIS
Reconstructs a matrix from its singular values and singular vectors created by SVDPack.
USGAE
svdpackout.pl [OPTIONS] lav2 lao2
INPUT
Required Arguments:
lav2
Binary output file created by SVDPack's las2
lao2
ASCII output file created by SVDPack's las2
Optional Arguments:
--rowonly
Only the row vectors are reconstructed. By default, svdpackout reconstructs entire matrix.
--format FORM
Specifies numeric format for representing output matrix values. Following formats are supported with --format :
iN - Output matrix will contain integer values each occupying N spaces
fM.N - Output matrix will contain real values each occupying total M spaces of which last N digits show fractional part. M spaces for each entry include the decimal point and +/- sign if any.
Default format value is f16.10.
Other Options :
--help
Displays this message.
--version
Displays the version information.
OUTPUT
svdpackout displays a matrix reconstructed from the Singular Triplets created by SVD. By default, entire matrix (product of left and right signular vectors and singular values) is reconstructed. When --rowonly is ON, only the reduced row vectors are built.
