ddm.fitting.doubleExp#

ddm.fitting.doubleExp(t, tau1, tau2, n, S1, S2)[source]#

Function for single exponential DDM fits

Parameters:

  • t (array_like) – array of the lag times

  • tau1 (float) – decay time for first exponential

  • tau2 (float) – decay time for second exponential

  • n (float) – fraction of dynamics for first exponential

  • S1 (float) – stretching exponent for first exponential

  • S2 (float) – stretching exponent for second exponential

Return type:

theoretical double exponential ISF for given parameters
