For ListInterpolation, you supply either a list of function values or an array of function values. Values of independent variables are assigned as either the integer value of the position of the function values you supplied or a linear mapping of these integer values to a range you specify. In all cases, ListInterpolation assumes the array of function values you supply are uniformly sampled. For Interpolation, you can supply both the value of the independent variables and the function values. This permits interpolation of non-uniformly sampled data, something not possible with ListInterpolation.
