CHI2GOF test response

Hi,

I'm trying to perform a chi2test and I'm not able to
interpret the result of tis function.

Here is the console window (lat is my test distribution):

nf = normfit(lat);
[h,p, stats] = chi2gof(lat,'cdf',@(x) normcdf(x,nf),
'nbins', 30, 'nparams',2)

h = 0
p = NaN
stats =

chi2stat: 1.3047e+003
df: 0
edges: [189.5294 225.3531 547.7660]
O: [3104 1893]
E: [1.8685e+003 3.1285e+003]

------------------

I don't understand how p could be "NaN" when h is equal to 0
(hypothesis not rejected).

If someone could help me it will be great.

Thanks.

Gael.
