Ok yes, thanks for your answer. it helped me tackling this problem.
Actually, the problem was residing in the bad writing of the optional
arguments. I was passing "standard" float numbers to variables defined as
Arrays{Float64,N}...
The proper definition of this function is:
function gaussianarea(Amplitude::Array{Float64},HWHM::Array{Float64};
eseAmplitude::Array{Float64} = [0.0], eseHWHM::Array{Float64} = [0.0])
Thanks again, I've been scratching my head on this problem!
