mdreg.quad

mdreg.quad(t, S0, R, A)

Quadratic function.

\[S(t) = S0(1 + Rt + At^2)\]

Parameters:

• t (array) – array of time points

• S0 (float) – signal scaling factor

• R (float) – relaxation rate in units 1/[t]

• A (float) – amplitude of quadratic term in units of 1/[t]^2

Returns:

Signal versus time, same size as t.

Return type:

numpy.ndarray
