f can only be evaluated successfully for numeric arguments so restrict it.. f[r_?NumericQ] := NIntegrate[r + s, {s, 0, 1}] g = FunctionInterpolation[f[r], {r, 0, 1}] Bob Hanlon ---- gac <g.crlsn at gmail.com> wrote: ============= f[r_] := NIntegrate[r + s , {s, 0, 1}] g = FunctionInterpolation[f[r], {r, 0, 1}] Can anyone explain why this works, yet I get the msg: NIntegrate::inumr: "The integrand r+s has evaluated to non-numerical values for all sampling points in the region with boundaries {{0,1}}." Can the statements be reformed to avoid the msg? Thanks. Glenn
