Map a function to each element of a matrix?

Is there a direct way to apply a function to each entry of a matrix and return the resulting matrix?

A = matrix([[1,2],[3,4]])
B = matrix([[j^2 for j in i] for i in A])

Not terribly hard, but it's not ideal.

sage: A = matrix([[1,2],[3,4]])
sage: f(x)=x^2                 
sage: A.apply_map(f)           
[ 1  4]
[ 9 16]
