求矩阵奇异分解svd算法

#-----------------------------------
# Input file used for SVDRUN script
#-----------------------------------
#
# DESCRIPTION OF FIELDS:
#-----------------------------------------------------------------------------
#
# NUM --> Run number (1,2,3,...).
#
# CDE --> SVDPACKC code (i.e. las1, bls1, las2, bls2 etc.).
#
# FNM --> Sparse Matrix datafile (i.e. belladit, belladit, etc.).
#         (Path to datafiles specified in svdrun script)
#
# MXI --> Maximum number of iterations for method.
# 
# TRP --> Number of singular triplets desired.
#
# SUB --> Maximum subspace dimension.
#
# BSZ --> Initial blocksize size (if applicable).
#
# RED --> Residual norm reduction factor for initiating shifting. (tms1,tms2)
#
# RITZ --> Controls use of ritz shifting (0=no,1=yes). (tms1,tms2)
#
# ACC --> Accuracy (residual tolerance)
#
# VEC --> Compute singular vectors also? (TRUE/FALSE)
