Constructor & Destructor Documentation

ThreeCSpike() [1/3]

mspass::algorithms::deconvolution::ThreeCSpike::ThreeCSpike	(	mspass::utility::dmatrix &	d,
		int	k
	)

Construct a spike from the vector sample at column k.

                                          {
  try {
    int i;
    for (i = 0; i < 3; ++i)
      u[i] = d(i, k);
    col = k;
    for (i = 0, amp = 0.0; i < 3; ++i)
      amp += u[i] * u[i];
    amp = sqrt(amp);
  } catch (...) {
    throw;
  };
}

ThreeCSpike() [2/3]

mspass::algorithms::deconvolution::ThreeCSpike::ThreeCSpike	(	int	k,
		const double	u0,
		const double	u1,
		const double	u2
	)

Construct a spike from explicit three-component amplitudes.

                                          {
  col = k;
  u[0] = u0;
  u[1] = u1;
  u[2] = u2;
  amp = sqrt(u0 * u0 + u1 * u1 + u2 * u2);
}
