How to calculate multiple array at once?

Hi Guys! I'm trying to do a MeanVoltage = mean(B0006.cycle(1:20).data.Voltage_measured) to store 1x20 data of mean voltage from B0006.cycle(1).data.Voltage_measured to B0006.cycle(20).data.Voltage_measured. Any recommendation? Thank you in advance!

PS: I got 1200+ data in the actual file, too much work to do it line by line.

load NEEDHELP

n = numel(TEST);
meanVolt = zeros(1,n);

for j = 1:n
    meanVolt(j) = mean(TEST(j).data.Voltage_measured(1:20));
end

Try this:

s = load('needhelp.mat')
B0006 = s.TEST % Array of 20 structs
% Wants MeanVoltage = mean(B0006.cycle(1:20).data.Voltage_measured);
% However, there is no cycle field.  So try it this way:
for k = 1 : length(B0006)
	MeanVoltage(k) = mean(B0006(1).data.Voltage_measured);
end
MeanVoltage % Report to command window.
