Description

The operator should add unity times the scalar to the matrix. For example adding the unit matrix to matrix A then becomes A += 1. I currently use the following implementation:

  template<typename K, int n>
  FieldMatrix<K, n, n> &
  operator+=(FieldMatrix<K, n, n> &M, K scalar)
  {
    for(int i = 0; i < n; ++i)
      M[i][i] += scalar;
    return M;
  }
