-
create_two_time_correlation_matrix(ddm_variability, number_of_frames, q_index)¶ Create two-time correlation matrix
After generating the DDM matrix as a function of time lag as well as of time, can use this function to generate a 2D two-time correlation function for a particular wavenumber.
- Parameters
ddm_variability (xarray dataset) – Results of function ‘variationInDDMMatrix’ in ‘ddm_analysis_and_fitting’ code
number_of_frames (int) – Number of frames of movie analyzed
q_index (int) – Index of the wavenumber array
- Returns
twotimecorrelation – Two time correlation function
- Return type
array
