Dear All
Most of the time I've no issue in mixing functions and vectorization, but here
I don't know why it does not work - one can see that using a vector I, the loop
is called only ounce and I do not understand why?
I've spent hours in such case showing I'm not fully at ease with it :-) :-)
Any explanation?
Thanks for your support
Paul
