I am using the following code to analyse some data stored in a structure:
for i=1:10; mean_value (i) = mean(getfield(Charge,strcat('Curve',int2str(i)))); end
"Charge" is the name of the structure, and "Curve" is each one of the 10 array of data inside it. So for this example, I get a vector with 10 elements that shows the average value of each group of data (the structure contains 10x(8670x1) elements). Now I want to take only the first 1416 elements of each array and to get its mean value. But I don't know how to do this.
Any suggestion? Thanks you so much!

If I understand your question, this may work...
for i=1:10; myData(:,i) = getfield(Charge,strcat('Curve',int2str(i))); end
mean_value = mean(myData); meanValueFirstBunch = mean(myData(1:1416,:));
You can reference the field of a structure dynamically with Charge.Curve1 or Charge.('Curve1') Loren has some nice blog posts on structures http://blogs.mathworks.com/loren/2009/05/20/from-struct-to-dataset/
i=0 for fname=fieldnames(Charge)' i=i+1; mean_value(i)=mean(Charge.(char(fname))(1:1416)); end
