成员函数说明

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

static

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

参数

m	the matrix whose sum of co-efficients has to be computed
no_diag	if true, diagonal entries are excluded from the sum

返回

the sum of co-efficients computed as \(\sum_{i,j}m_{i,j}\)

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

static

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

参数

b	the matrix-block whose sum of co-efficients has to be computed
