Averaging mutiple structures to get a single mean waveform

Hi,

I have a structure called Results.

Within this structure I have x amount of fields. Each field having a 1xn structure. I would then like to make an average waveform from the 1xn structure for each field.

Conceptually, this is a very basic thing to do, but struggling to apply it.

Many thanks,

The following code might help you:

clear all
a(1).waveforms = rand(101,1);
a(2).waveforms = rand(101,1);
a(3).waveforms = rand(101,1);

Results.a = a;
Results.b = a;
Results.c = a;

fieldNames = fieldnames(Results);

for i = 1:numel(fieldNames)
    res = arrayfun(@(x)x.waveforms,Results.(fieldNames{i}),'UniformOutput',false);
    resMat = cell2mat(res);
    avgWaveforms.(fieldNames{i}) = mean(resMat,2);
end
avgWaveforms

Refer to arrayfun & mean for more information and related examples.
