Time to compute one displacement profile averaged over 1000 trials. Ensemble lengths are varied between 2 and 300 A-lines. ‘PCDE – Eig’ denotes PCDE estimates when MATLAB function ‘eig’ is used to compute eigenvectors. Similarly, ‘PCDE – Eigs’ denotes PCDE estimates when MATLAB function ‘eigs’ is used to compute eigenvectors.
