pure virtual

◆ SetMatrixArray()

template<class Element >
TMatrixTBase< Element > & TMatrixTBase< Element >::SetMatrixArray ( const Element *  data,
Option_t option = "" 
)
virtual

Copy array data to matrix .

It is assumed that array is of size >= fNelems (=)))) fNrows*fNcols option indicates how the data is stored in the array: option =

  • 'F' : column major (Fortran) m[i][j] = array[i+j*fNrows]
  • else : row major (C) m[i][j] = array[i*fNcols+j] (default)

◆ Shift()

template<class Element >
TMatrixTBase< Element > & TMatrixTBase< Element >::Shift ( Int_t  row_shift,
Int_t  col_shift 
)
virtual

Shift the row index by adding row_shift and the column index by adding col_shift, respectively.

So [rowLwb..rowUpb][colLwb..colUpb] becomes [rowLwb+row_shift..rowUpb+row_shift][colLwb+col_shift..colUpb+col_shift]

Reimplemented in TMatrixTSym< Element >, and TMatrixTSym< Double_t >.
