I have a function of this type: f = 1 / (a.log(x)+b), and I need to find t-statistics for parameters a and b... How can I do this? Is it helpful to do this using curve fitting tool? Can you give me an example?

Do you have a recent version of the Statistics Toolbox available?
>> load census
>> d = dataset(cdate,pop);
>> nlm = NonLinearModel.fit(d,'pop ~ 1/(a*log(cdate)+b)',[1 1])
The output includes t statistics
