Hi everyone,
I am an R and MATLAB user who is moving to Julia. I am trying the Numeric
Extensions package. In the documentation (
http://numericextensionsjl.readthedocs.org/en/latest/functors.html), they
show an example of how to define a new functor:
type SqrDiff <: Functor{2} end
NumericExtensions.evaluate(::SqrDiff, x, y) = abs2(x - y)
However, when I try to apply this new functor, I get this result:
*julia> **type SqrDiff <: Functor{2} end*
*julia> **NumericExtensions.evaluate(::SqrDiff, x, y) = abs2(x - y)*
*evaluate (generic function with 143 methods)*
*julia> **x=ones(4)*5*
*julia> **y=ones(4)*2*
*julia> **map(SqrDiff(),x,y)*
*ERROR: SqrDiff not defined*
*julia> **map(NumericExtensions.SqrDiff(),x,y)*
*ERROR: SqrDiff not defined*
Any ideas about what the problem is? I have no problem with
*julia> **map(NumericExtensions.Multiply(),x,y)*
