Hi,
today I had a chat with Andreas, a new developer, and to revive the
habit of sending a summary of what is going on, I am sending this mail.
The task is #49 (unifying propagators), and was focused on making the
OperatorMatrix more accessible. Basic decisions:
* OperatorMatrix gets a new constructor that takes a single operator
and sets up a 1x1 matrix with this operator (to handle the trivial
case)
- invalid_argument exception if the operator is null
* OperatorMatrix gets a new constructor that takes a vector of vectors
of operators (rows in the matrix), and sets up the operator
- invalid_argument exception if all operators null
- invalid_argument exception if matrix not quadratic
- invalid_argument exception if wrong number of operators in a row
* add a new static variable that represents a null operator (null
pointer); supplying this operator in the second constructor signals
that this cell of the matrix is the zero operator.
* add a function getSize() to return the size of the OperatorMatrix
* add a function getOperator(uint row, uint column) that returns the
appropriate operator in this cell of the matrix
- invalid_argument exception if the row or column is out of range
