4.3.30. recalcvec.dat¶
This file is the outputted file for two vectors to recalculate the dynamical Green’s function by the Lanczos method. The file format is of the binary type. An example of the file format is as follows.
File name¶
##_recalcvec_rank_$$.dat
## indicates [string02] in a ModPara file and $$ is the number of rank.
File format¶
Line 1: [int01]
Line 2: [int02]
Lines 3 - 3+ [int02]: [double01] [double02]
Lines 4+ [int02] - 4+2 \(\times\) [int02]: [double03] [double04].
Parameters¶
[int01]
Type : Int
Description : The step for calculating dynamical Green’s functions by the Lanczos method \(N_d\).
[int02]
Type : Long Int
Description : The total number of targets of the Hilbert spaces.
[double01], [double02]
Type : Double
Description : The value of the vector \(\boldsymbol{v}_{k+1}\) for recalculating dynamical Green’s functions by the Lanczos method.[double01] and [double02] are a real part and an imaginary part of \(\boldsymbol{v}_{k+1}\), respectively. The fist component is not used for calculation.[double03], [double04]
Type : Double
Description : The value of the vector \(\boldsymbol{v}_{k}\) for recalculating dynamical Green’s functions by the Lanczos method.[double03] and [double04] are a real part and an imaginary part of \(\boldsymbol{v}_{k}\), respectively. The fist component is not used for calculation.
