Dear @paulremo,
thank you very much for improving the uq_postProcessInversion
function.
I had a look to the code and have tested it. Your new code works and fixes the issues with the prior predictive I mentioned, at least with my default UQLab version.
If one want sto use your new version of uq_postProcessInversion.m
with the current live version UQLab v1.3.0, one needs to replace also uq_display_uq_inversion.m
by its preview version in your post from June.
Greetings
Olaf
