=============
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?
