You're welcome. If you are looking to improve performance further, you
could add @inbounds and @simd macro calls, as seen
here:
As a proposal, this is what I would do, given you requirements:
function _scaleRestore!(Z, Zout, shift, stretch)
for j in 1:size(Z, 2), i in 1:size(Z, 1)
Zout[i, j] = Z[i, j] * stretch[j] + shift[j]
end
return Zout
end
scaleRestore!(Z::Vector, shift::Number, stretch::Number) =
I don't know of any way to accomplish what you want with a single method
signature. I don't see how Union can help you, because you would not be
able to disallow (Vector x Vector x Vector) input, for example. You
normally achieve this in Julia by writing two separate methods, which is
what you
Hmm. I slightly misread the way you had set up your code. I thought you
wanted your code to cover three cases: all scalar, one vector - two
scalars, and one matrix - two vectors.
So to be clear: defining the function:
scaleRestore(a, b, c) = a .* b' .+ c'
covers both your cases and then some
This should work for the three cases you have set up:
f_scaleRestore(a, b, c) = a .* b' .+ c'
