Like the raw iterator, the indexed iterator is a method for accessing all entries in the matrix in some unspecified order.
At each position of the the indexed iterator, it also provides the row and column indices of the currently referenced entry. This is provided through it's rowIndex()
and colIndex()
functions.

A BlasMatrix
is a matrix of _Field::Element
, with the structure of BLAS matrices. It is basically a vector of _Field::Element
. In the Mother model, a BlasMatrix
is allocated by the user.
Bug: necessitates the inclusion of those things after of before. We should not include directly this but just the matrices and they automatically need their domain (for now)
