#78 @stk_sampcrit_eqi/set.m: in Matlab, norminv is in the stat toolbox

[Julien Bect]

Failing test in Matlab R2008a without the stat toolbox:

>> stk_test stk_sampcrit_eqi
***** test F.quantile_order = 0.9;  assert (F.quantile_order == 0.9)
!!!!! test failed
Undefined function or method 'norminv' for input arguments of type 'double'.

The stat toolbox is supposed to be an optional dependency in STK, so this is a problem.

In this revision

the "norminv" function was changed by an expression using "erfcinv" function.

Is it better ?

[Julien Bect]

Yes, it is better at least for Matlab:

I will check in old releases of Octave and close the ticket if it's ok.

Hmmmmm... erfcinv was introduced in Octave 3.8.0... Here is the final fix:
