Hi everyone,
I have 65 mat files with different names and each mat file is 1x1 struct, contains information as longitude, latitude, year(335x1), month(335x1) etc.
So how can i combine them as a single mat file which should have first row as a information of first mat file, second row as a information of second mat file, until 65 rows of each mat file?
I would be very pleased if you have any idea about how to do it?

You did not explain, how a list of the files names can be obtained. I guess, that they can be found in the same folder:
Folder = 'C:\your\folder';
Files = dir(fullfile(Folder, '*.mat'));
DataC = cell(1, numel(Files));
for iFile = 1:numel(Files)
aFile = fullfile(Folder, Files(iFile).name);
DataC{iFile} = load(aFile);
end
Data = cat(2, DataC{:});

files contains structs with a field name and with subfields of longitutde latitude datetime and observation as well. Expected output is having one mat file that each file with its subfields in a row, so that i can just call with the row order.
Has it become more clear?

What are "subfields in a row"? Fields do not have an orientation. What is "calling with the row order"?
I assume, you want to create either a struct array, or to write a text file containing rows.
