1 Changed transition matrix sampling procedure to try to avoid Markov chains
|
|
samer@11
|
2 with mupltiple stationary distributions (fixed points).
|
|
samer@11
|
3 To this end:
|
|
samer@11
|
4 * mc_fixpt has a tolerance parameter - all eigenvalues within this much of
|
|
samer@11
|
5 1 are considered fixed points.
|
|
samer@11
|
6 * mc_global_info1 (replaces mc_global_info) now checks that transition matrix
|
|
samer@11
|
7 has only one fixed point and returns a flag if this is the case
|
|
samer@11
|
8 * sampling logic is in mt_resample - transition matrices not passing uniqueness
|
|
samer@11
|
9 test are either resampled (method 1) or perturbed (method 2)
|
|
samer@11
|
10 * mt_init has new parameters, ErgMethod to select conditioning method and
|
|
samer@11
|
11 tolerance to pass to mc_fixpt.

|
15 * Information measures are now displayed in bits, not nats.
|
|
samer@11
|
16 * Clicking on the title bar of a displayed transition matrix now displays
|
|
samer@11
|
17 information about its eigenvalues and eigenvectors (mt_show_transmat.m).
