Hello,
I have a wro sets of data (big structures) named 'L_Data' and 'R_Data' and I am trying to select R or L acoording to a list of subject injury side.
I am trying to avoid using If statements to increase efficiency as much as possible as this is a large set of data.
Is there a way to access 'L_Data' and 'R_Data' by creating:
L_Data = struct(Subject1,Subject2)
R_Data = struct(Subject1,Subject2)
SubjectSide = 'L'
VarName = [SubjectSide,'_Data']
Output = mean( (VarName).Subject1 , 2)
Thank you.

Can you dynamically create and access variables with numbered names like x1, x2, x3, etc. or similar names like L_Data and R_Data? Yes.
Should you do this? The general consensus is no. That Answers post explains why this is generally discouraged and offers several alternative approaches.
