Hello,
I encountered some strange behaviour of NIntegrate when I use a
somewhat neseted structure of several - in my example of two -
NIntegrate[] functions
NIntegrate[NIntegrate[y,{x,-1,1}],{y,-1,1}]
This gives me the error
NIntegrate::"num Integrand y is not numerical at {x) = 0
Why does the inner NIntegrate function not know, what value is
currently assigned to y...
I hope someone can shed a little light on that seemingly paradoxical
behaviour.
thanks in advance
Eckhard
