[julia-users] how to compute the maximum value of an object's attribute

[Michela Di Lullo]

Hello everyone, 

I have to compute the maximum value of tau_max, attribute of TUnit which is 
declared as follows:

immutable TUnit

    Node::Int16

    a::Float64

    b::Float64

    c::Float64

    inf::Float64

    sup::Float64

    ton::Int16

    toff::Int16

    storia0::Int16

    pt0::Float64

    rampa_up::Float64

    rampa_dwn::Float64

    rampa_up_str::Float64

    rampa_dwn_str::Float64

    SUC_C::Float64

    tau_max::Int16

end    


TUnitS = Array(TUnit,size(generators,1))


for j in 1:size(generators,1)

    #println(generators[j,1:end])

    #FL:This call the contructor, see all the discussion in the manual 
"Parametric Constructors" section

    #to understand the whole (complex story) of the syntax with "..."

    TUnitS[j]   = TUnit(generators[j,1:end]...)

    println("TUnit = ", j, "\t Node[$j]= ", TUnitS[j].Node, "\t a[$j] = ", 
TUnitS[j].a, "\t ...", "\t tau_max[$j] = ", TUnitS[j].tau_max)

end


I tried with both maximum(TUnitS.tau_max) and maximum(TUnitS[j].tau_max, 
j=[1:gmax]), but it doesn't work..


Any idea about how to make it? 


Thank you very much for any suggestion,
