infinityNorm method

double infinityNorm()

Returns the infinity norm of the matrix. Used for numerical analysis.

Implementation

double infinityNorm() {
  var norm = 0.0;

  for (var column = 0; column < 16; column += 4) {
    final columnNorm =
        this[column].abs() + //
        this[column + 1].abs() +
        this[column + 2].abs() +
        this[column + 3].abs();

    norm = columnNorm > norm ? columnNorm : norm;
  }

  return norm;
}
