This works fine for a single stretched exponential, but when trying to use two it throws an error.

  • Status changed from new to inprogress

Refs #8827 Add generic plotting functions to IndirectCommon.

These will be useful when working on ticket #8236.

  • Blocking 8236 added

(In #8236) I added some useful functions into IndirectCommon in ticket #8827 that should make this ticket easier.

  • Status changed from inprogress to verify
  • Resolution set to fixed

Run FuryFit and choose the fit function: 1 exponential, 1 stretched exponential. Choose to plot Beta and run a sequential fit. This should now work. Also check the other plot options in Fury work.

comment:7 Changed 7 years ago by Roman Tolchenov

The plots seemed to work but I couldn't get a good fit with 1 exp and 1 stretched exp. I think the wiki page needs and example for the starting values for this case.
