just one suggestion. The function name may be modified to make more
clear what it's for. We already have the built-in function iwishart().
So why not name the proposed function drawnormiwishart()? Personally I
would even name it drawnormal_iwishart() for readability purposes.
I agree the name is suboptimal, but maybe we should rather try to
describe what it is for: Namely re-drawing for a multi-equation system.
Perhaps something like 'syscoeffdraw'? That would also leave the door
open for other underlying distributions in the future. (Would that be a
likely or sensible generalization?)

I could have a look at it during the next 2 days.
Ok thanks.
(Please expect that editing the produced plots is likely going to fail.
Jack had commented that it might still be useful.)
cheers
