Dear @YuanXi_Wu
Thank you for providing the data and pointing out this problem. We have investigated the issue and there is indeed a bug in UQLab. Fortunately, the problem is small and can be easily fixed.
Navigate to the following file in your UQLab installation:
path_to_uqlab\modules\uq_input\builtin\uq_default_input\uq_initialize_uq_default_input.m
.
and then change line 100 from
uBounds(2) = min(KSPar) + ks.Nstd*stdKSPar;
to
uBounds(2) = max(KSPar) + ks.Nstd*stdKSPar;
Best regards
Styfen
