Detailed Description

template<typename T>
class ModuleIO::csrFileReader< T >

Class to read CSR file.

This class is used to read CSR file the default format is like:

STEP: 0
Matrix Dimension of S(R): 4
Matrix number of S(R): 2
0 1 1 2            # (0,1,1) is the R coordinate, 2 is the number of non-zero elements
 4.00e+00 7.00e+00 # non-zero elements
 3 2               # column indices
 0 1 2 2 2         # row pointer
0 0 0 3            # the second R coordinate and number of non-zero elements
5.00e+00 6.00e+00 1.00e+01
2 3 3
0 0 0 2 3

It will store the R coordinates and sparse matrices as two vectors. One can use getter functions to get the R coordinates and sparse matrices, and related info including step, matrix dimension, number of R.
