Dear colleagues:

I have problems computing the inverse-chi-squared distribution in SciLab with

cdfchi = cumulative distribution function chi-square distribution.

I want to generate the 95% confidence limit of small numbers like below


number n        lower limit     upper limit
0       0.00    3.69
1       0.03    5.57
2       0.24    7.22
3       0.62    8.77
4       1.09    10.24
5       1.62    11.67

and this is easily calculated in EXCEL with conf=0.95 and

=CHIINV(1-(1-conf)/2,2*n)/2 for the lower limit; and

=CHIINV((1-conf)/2,2*(n+1))/2 .

But how do I do this in SciLab?
