data = Sort[RandomReal[{0, 10}, {8, 2}]]; f = Interpolation[data]; Plot[f[x], {x, Min[data[[All, 1]]], Max[data[[All, 1]]]}, Epilog -> {Red, AbsolutePointSize[4], Point[data]}, Frame -> True, Axes -> False, PlotRange -> All] Bob Hanlon ---- girl17 <irexxy at gmail.com> wrote: ============= So, I have a list for tabulated function like that: {{x1,y1},{x2,y2},...,{xn,yn}}, where x(i+1)-xi are not equal for all i. I want to get an interpolated function for that array and to use this function in this way: intFucn[x], where x1<=x<=xn. I tried to use ListInterpolation[], but it works only for 1D lists, i.e. in case if x(i+1)-xi are equal for all i. Is there any solution for this problem?
