TMatrixTSparse

Template class of a general sparse matrix in the Harwell-Boeing format

Besides the usual shape/size decsriptors of a matrix like fNrows, fRowLwb,fNcols and fColLwb, we also store a row index, fRowIndex and column index, fColIndex only for those elements unequal zero:

fRowIndex[0,..,fNrows]: Stores for each row the index range of
the elements in the data and column array
fColIndex[0,..,fNelems-1]: Stores the column number for each data
element != 0

As an example how to access all sparse data elements:

for (Int_t irow = 0; irow < this->fNrows; irow++) {
const Int_t sIndex = fRowIndex[irow];
const Int_t eIndex = fRowIndex[irow+1];
for (Int_t index = sIndex; index < eIndex; index++) {
const Int_t icol = fColIndex[index];
const Element data = fElements[index];
printf("data(%d,%d) = %.4e\n",irow+this->fRowLwb,icol+
this->fColLwb,data);
}
}

When checking whether sparse matrices are compatible (like in an assigment !), not only the shape parameters are compared but also the sparse structure through fRowIndex and fColIndex .

Several methods exist to fill a sparse matrix with data entries. Most are the same like for dense matrices but some care has to be taken with regard to performance. In the constructor, always the shape of the matrix has to be specified in some form . Data can be entered through the following methods :

  1. constructor
    TMatrixTSparse(Int_t row_lwb,Int_t row_upb,Int_t dol_lwb,
    Int_t col_upb,Int_t nr_nonzeros,
    Int_t *row, Int_t *col,Element *data);
    It uses SetMatrixArray(..), see below
  2. copy constructors
  3. SetMatrixArray(Int_t nr,Int_t *irow,Int_t *icol,Element *data) where it is expected that the irow,icol and data array contain nr entries . Only the entries with non-zero data[i] value are inserted. Be aware that the input data array will be modified inside the routine for doing the necessary sorting of indices !
  4. TMatrixTSparse a(n,m); for(....) { a(i,j) = .... This is a very flexible method but expensive :
    • if no entry for slot (i,j) is found in the sparse index table it will be entered, which involves some memory management !
    • before invoking this method in a loop it is smart to first set the index table through a call to SetSparseIndex(..)
  5. SetSub(Int_t row_lwb,Int_t col_lwb,const TMatrixTBase &source) the matrix to be inserted at position (row_lwb,col_lwb) can be both dense or sparse .
