I am looking for the equivalent command in Maple to the Mathematica command # which takes the first argument of a pure function. Is there any such equivalent, and if so what is it?

I have a function written that takes a column vector and returns a column vector. I would like to apply this function to a matrix and have it run on the columns of the matrix. Is there a way to do this like in Mathematica? I have tried the Map and Map2 commands but they only apply a function entry by entry. I need a way to evaluate a vector function on the first through last columns of the matrix.
