## Member Function Documentation

 static T compute ( SGMatrix< T > mat, bool no_diag )
static

Method that computes the sum of co-efficients of SGMatrix using Eigen3

Parameters
 m the matrix whose sum of co-efficients has to be computed no_diag if true, diagonal entries are excluded from the sum
Returns
the sum of co-efficients computed as $$\sum_{i,j}m_{i,j}$$

Definition at line 241 of file Sum.h.

 static T compute ( Block< SGMatrix< T > > b, bool no_diag )
static

Method that computes the sum of co-efficients of SGMatrix blocks using Eigen3

Parameters
 b the matrix-block whose sum of co-efficients has to be computed no_diag if true, diagonal entries are excluded from the sum
Returns
the sum of co-efficients computed as $$\sum_{i,j}b_{i,j}$$
