I have a Vector of Data. and i want to do a fitting to the Vector. but I want the fit to be in the shape of:
A/x+B/x^2+C/x^3...
is there any Known function I am missing?or do i need to write my own code. if so anyone is familiar with a good way to do that?

If you have the Statistics Toolbox, you can use the function nlinfit() to do that.

Hi,
First solution: replace x by y=1/x, then use polyfit to fit your data with respect to y.
and type
showfit ('A/x+B/x^2+C/x^3')
