matlab structs cell-arrays MATLAB

I can't seem to get I'm attempting to set up I'm working on a project and hit a roadblock. I just started working with I tried several approaches but none seem to work. I'm working with an scenario when trying to access dynamically named fields in a cell array of structs in MATLAB. I have a struct array where each struct contains different fields, and I'm trying to loop through these structs to extract values based on dynamic field names. Here's a snippet of what I've tried: ```matlab % Sample struct array data(1).name = 'Alice'; data(1).age = 30; data(2).name = 'Bob'; data(2).age = 25; data(2).height = 175; dynamicField = 'height'; % Accessing the dynamic field in a loop for i = 1:length(data) if isfield(data(i), dynamicField) fprintf('%s: %d ', data(i).name, data(i).(dynamicField)); else fprintf('%s: Field not found ', data(i).name); end end ``` However, when I run this code, I get the output: ``` Alice: Field not found Bob: 175 ``` I expected to see 'Alice: Field not found' since Alice does not have a 'height' field, which is correct, but I get an unexpected message when I try to print values. I noticed that if I set `dynamicField = 'age';`, it works as expected. Am I missing something about how cell arrays and dynamic field referencing works in MATLAB? I would appreciate any insights into this behavior and how to ensure I correctly reference fields that may not exist in some structs. Any ideas what could be causing this? I'm working with Matlab in a Docker container on Windows 10. What's the correct way to implement this? Any help would be greatly appreciated!
