How to write in short form?

Greetings,

How can I write the following command in a short form to avoid this repetition?

 clear

 %%load all Residual .mat files

 s = what; %look in current directory
 %s=what('dir') %change dir for your directory name 
 matfiles=s.mat
 for a=1:numel(matfiles)
 load(char(matfiles(a)))
 end

 SDED = vertcat(SDED1,SDED2,SDED3,SDED4,SDED5,SDED6, ...
               SDED7,SDED8,SDED9,SDED10,SDED11,SDED12);

 save SDED.mat SDED

Thank you for the help

s = dir('*.mat');
C = cell(1, numel(s));
for a = 1:numel(s)
  Data = load(s(a).name);   % [EDITED]
  % Now assuming that "SDED1" e.g. is the only variable in the MAT file:
  C(a) = struct2cell(Data);
end

SDED = vertcat(C{:});
save SDED.mat SDED

thank you for your help Jan I am getting this error

 Cell contents reference from a non-cell array object

I changed the curly brackets, but it still warns me about the error

If you know that the SDED are numbered from 1 to 12:

 s = sprintf('SDED%d, ', 1:12);
 eval(['SDED = vertcat(' s(1:end-2) ');'])

or if you want to use all SDED variables in the workspace:

x = whos('SDED*');
s = sprintf('%s, ', x.name);
eval(['SDED = vertcat(' s(1:end-2) ');'])

Better to avoid eval and simply load the data into one structure:

S = load(...);

Why eval is poor code that should be avoided:
