I have a list of points:
I then define a function NN[x] that returns the linearly interpolated
value at x:
linN = Interpolation[lst, InterpolationOrder -> 1];
However, if I want to make the integral a function of the upper limit,
and plot it:
I get this message:
"NIntegrate::slwcon: Numerical integration converging too slowly; suspect one \
of the following: singularity, value of the integration being 0, oscillatory \
integrand, or insufficient WorkingPrecision. If your integrand is oscillatory \
try using the option Method->Oscillatory in NIntegrate."
Maybe there's nothing wrong with the result, but I'm not sure. And the
message is annoying, too.
Does anyone know how to make Mathematica do the work without complaining?
I appreciate it.
