Hi all,

I have a question that I have not been able to work out myself, and so 
put it to the group to help. I have a set of data points in a table (2 
columns {{x1,y1},{x2,y2},....,{xn,yn}}) I have performed a fit to the 
data and have a function f[x] which I would now like to evaluate at each 
data point (column 1 of the first table) to get a new table 
{{x1,f[x1]},{x2,f[x2]},....,{xn,f[xn]}}. Is there a way to do this? I 
hope my request is clear

Best Regards
Michael
