SystemSolver constructor
SystemSolver({
- required RealMatrix matrix,
- required List<
double> knownValues, - double precision = 1.0e-10,
Given an equation in the form Ax = b
, A
is a square matrix containing
n
equations in n
unknowns and b
is the vector of the known values.
This class can only be built with square matrices. In particular:
- matrix is the matrix with the equations;
- knownValues is the vector with the known values.
An exception of type SystemSolverException is thrown if the matrix is not square.
Implementation
SystemSolver({
required this.matrix,
required this.knownValues,
this.precision = 1.0e-10,
}) {
// Only square matrices are allowed.
if (!matrix.isSquareMatrix) {
throw const SystemSolverException('The matrix must be square');
}
// The vector of known values must match the size of the matrix.
if (matrix.rowCount != knownValues.length) {
throw const SystemSolverException(
'The known values vector must have the '
'same size as the matrix.',
);
}
}
