MATLAB: Retrieving data from structure

structures

I am having a weird issue when trying to get data from a structure.

I am using dir to get folder names into the variable FolderNames, I then need to extract the names from there, eg. via.

FolderNames.name{1}

or something? (I have been away from coding for a little while), but I keep running intro trouble. When I run the above code it says "Expected one output from a curly brace or dot indexing expression, but there were 21 results.". But I dont know how to get only result 1 (or 2 or 3, etc.)

Try

A{3}=[3 4 5 6; 3 4 5 6; 3 4 5 6; 3 4 5 6; 12 16 25 24];
A{4}=[4 5 6 7; 4 5 6 7; 4 5 6 7; 4 5 6 7; 16 20 24 28];
B=cell2mat(A);
[m,n]=size(A{1});
b=B(m,n*(1:n));
[b,ind]=sort(abs(b));
ind=ind(1:2);
SelectA=A(ind);
celldisp(SelectA);
