pymor.algorithms.lincomb.assemble_lincomb(operators, coefficients, solver=None, name=None)

Try to assemble a linear combination of the given operators.

Returns a new Operator which represents the sum

c_1*O_1 + ... + c_N*O_N

where O_i are Operators and c_i scalar coefficients.

This function is called in the assemble method of LincombOperator and is not intended to be used directly.

To form the linear combination of backend Operators (containing actual matrix data), _assemble_lincomb will be called on the first Operator in the linear combination.

Parameters:

• operators – List of Operators O_i whose linear combination is formed.

• coefficients – List of the corresponding linear coefficients c_i.

• solver – Solver for the assembled operator.

• name – Name of the assembled operator.

Returns:

The assembled |Operator|.
