I have defined a function- >>f=inline('x*y','x','y') Now when i take log of this- >>logarithm=inline(log(f(x,y)),'x','y') Matlab simply shows log(x.*y) HOW CAN I GET THE ANSWER "logx+logy" instead?

You might be able to do it with the symbolic toolbox, though I would have to experiment to figure out how messy it is.
You should not be writing any new inline() unless you need backwards compatibility with something already written. Anonymous functions have replaced inline()
