Trimming structure of Arrays

Hi Guys

I have a structure like this:

Data =

          dateTime: [4906x1 double]
       aircraftLat: [4906x1 double]
      aircraftLong: [4906x1 double]
       aircraftMSL: [4906x1 double]
     aircraftSpeed: [4906x1 double]
    aircraftCourse: [4906x1 double]
            gcsLat: [4906x1 double]
           gcsLong: [4906x1 double]
            gcsMSL: [4906x1 double]
             antAz: [4906x1 double]
             antEl: [4906x1 double]
              rssi: [4906x1 double]

I'd like to take the first 5 elements of each array and remove. Is there a neat solution for this? Or would I have to go into each array eg. Data.aircraftLat(1:5) = [], etc.

Thanks

Amir

DataField = fieldnames(Data);
for iField = 1:numel(DataField)
   aField        = DataField{iField};
   Data.(aField) = Data.(aField)(5:end);
end

Data=structfun(@(x) ( x(6:end) ), Data,'UniformOutput', false);

It looks like all you arrays are the same size. You may want to consider a structure array instead of a structure with lots of arrays. This way you could then just do:

Data = Data(6:end);

to remove the first 5 elements.
