The functionality of NumericalMath`ListIntegrate` is now accessible by using the built-in Mathematica kernel functions Integrate and Interpolation.
This gives an approximation to the integral of the function that produced the list of data:
Version 5.2
![<< NumericalMath`ListIntegrate`;
data = Table[n^2, {n, 0, 7}];
ListIntegrate[data, 1]](Files/ListIntegrate.zh/legacy_1.gif)
data = Table[{n, n ^ 2}, {n, 0, 7}];
Integrate[Interpolation[data, InterpolationOrder -> 2][x], {x, 0, 7}]
