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

mat	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 \(\sum_{i,j}b_{i,j}\)
