Thread[] or Map[] will usually do this. If you have trouble with this method (depends on what's in the function), you can also use: f[#]&/@v which will Map f over the first level in v.

I now want to apply that function to each element of a vector, v, of length n, as in newVector = f[v], but I get an error because my function f does not thread over the elements of the vector as do built-in Mathematica functions such as Log[]. How can I get my function to apply to each element of my vector? Regards, Greg
