Combine 2 Structures / have a nice weekend

As you can see here, i am trying to combine two structures. It works ! But is there a faster way ?

 Variable = length(OldInputData)

                    for k = 1:length(InputData)
                    OldInputData(Variable + k).shotnumber = InputData(k).shotnumber
                    OldInputData(Variable + k).UsedAmp = InputData(k).UsedAmp  
                    OldInputData(Variable + k).ClosestAmp = InputData(k).ClosestAmp
                    OldInputData(Variable + k).OptimalAmp = InputData(k).OptimalAmp
                    OldInputData(Variable + k).Factor = InputData(k).Factor 
                    OldInputData(Variable + k).ReadSSX = InputData(k).ReadSSX
                    OldInputData(Variable + k).ssx_t = InputData(k).ssx_t 
                    end

Have a nice weekend!

you can go

 OldInputData = [OldInputdata InputData]

only if they contain the same structures inside. Since you're just concatenating it should work fine. if there is a new structure it'll add that to the others but be empty.

see example:

for i =1:10
    old(i).shot = randi(10);
    old(i).used = randi(10);
    old(i).closest = randi(10);
    old(i).optimal = randi(10);
    old(i).factor = randi(10);
    old(i).ssx= randi(10);
    old(i).lkjasf = randi(10);
end
    old = [old old]

then i can see that

i should be able to check that old(1) and old(11), 2 and 12, etc. should have the same stuff.

if we add a new structure element (is that the right term?) to it like

i = i+1;
    old(i).shot = randi(10);
    old(i).used = randi(10);
    old(i).closest = randi(10);
    old(i).optimal = randi(10);
    old(i).factor = randi(10);
    old(i).ssx= randi(10);
    old(i).lkjasf = randi(10);
    old(i).asdfasdf = 2

then all 1:20 has a new asdfasdf = [] to them.

I did something very similar myself just the other week, but since that seems to be a ready-built explanation of various methods there isn't much point me fishing out whatever method I ended up using!
