s_c_1 is a 1*96 row vector.It is stored as a structure variable of 1*1. How do i access the data in the vector? I have tries to do so using a loop in line 8, but its giving an error :" reference to non-existent field name".

folder='C:\Users\Divya\Desktop\matfiles\';

s=dir(folder);
s([s.isdir])=[];

rows=length(s);

s_c=fullfile(folder,'1_1_1.mat');
s_c_1=load(s_c);
disp(s_c_1);

    for i=1:1:96
  disp(s_c_1(i).name);
  end

I think s_c_1 is stored as a cell array of 1*1

s_c_1 is stored as a cell array of 1*96 not 1*1

"s" is the structure that has the field named "name".

The fieldnames for "s_c_1" are the names of the variable that are in the .mat file. "s_c_1" will not be a cell array.

After the load() statement, examine

class(s_c_1)
fieldnames(s_c_1)
