How to extract specific struct data from multiple mat files? Please help. Thank you so much.

I have the following 5 mat files for 5 samples of data type 0. These mat files contain lot of data structure and variables. I want to extract a specific struct type data named ap_struct from each these mat files using loop. How can I do that? Thank you so much.

N = 5;
ap_structs = cell(N,1);
for K = 1 : N
filename = K + "pbs0.mat";
datastruct = load(filename, 'ap_struct');
ap_structs{K} = datastruct.ap_struct;
end
%output is cell array ap_structs
Here, I do not assume that the ap_struct in the different files have exactly the same fields in exactly the same order.
If they do contain the same fields in the same order then instead you can use
N = 5;
clear ap_struct;
for K = N : -1 : 1
filename = K + "pbs0.mat";
datastruct = load(filename, 'ap_struct');
ap_struct(K) = datastruct.ap_struct;
end
%output is non-scalar struct ap_struct
