Objet : [mg49464] Applying my function to elements of a vector


Hello everyone,

Say I've created a function, f[x_], which accepts a single scalar as
its argument.  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
