Sorry if I misunderstood the problem but would it be something like the following? x=RandomReal[{0,10},{20}]; (*Generate random x*) data=Transpose[{x,x^2}] (*The function is now y=x^2*) intFunc=Interpolation[data]; Show[ListPlot[data],Plot[intFunc[x],{x,0,10}]] It worked over here Hope it helps, Gabriel On Fri, Jan 14, 2011 at 9:16 AM, 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? > >
