[Help-gsl] data intersection

[dantian]

Dear all,

I've 2 set of data with different sizes and different not constant 
intervals.
There are  X and Y columns.
so, I'm wondering whether GSL provides tools to get the intersection point.
I thought about getting get the minimum of the data difference but 
intervals are different.
May be I can use spline interpolation and create a new data set with 
same X values ..... I don't know if it's possible.
Any idea?
Thanks in advance,
Best,

               Eric.
