Hi all,
I have three *.mat files as shown under the Current Folder space in the image. Each mat file has two structures named Config and Waves_Data as shown in the Workspace. Under the Waves_Data, there are several Fields as shown in Variables section. I need to extract Time and Status_ Amplitude fields from each *.mat file and append them one after the other to have a combined Time and combined Status_Amplitude.
How can I put these into a loop. Appreciate your thoughts.
Thank you

D = 'absolute/relative path to where the files are saved';
S = dir(fullfile(D,'*.mat'));
N = numel(S);
for k = 1:N
F = fullfile(D,S(k).name);
T = load(F);
S(k).Time = T.Waves_Data.Time;
S(k).StAm = T.Waves_Data.Status_Amplitude;
end
Time = horzcat(S.Time) % or VERTCAT
StAm = horzcat(S.StAm) % or VERTCAT
