The following functions in scripts/statistics/distributions are implemented with loops which are slow in Octave.




The first three are problematic because they use a 'while (1)' construction and the stopping condition is not always met. For example,


will create an infinite loop that can only be broken with Ctrl-C.

At the very least, the 'while (1)' construction should be replaced with a for loop which will eventually terminate.

The best possible outcome would be to recode these entirely to get rid of the loops.
