for i=1:10001
new_cell{i}=vertcat(input_test1{i,1},input_test1{i,2},input_test1{i,3},input_test1{i,4},input_test1{i,5},inputs_test1{i,6},input_test1{i,7});
end
new_cell=new_cell'; % Transpose if you want
% Alternatively if you desire the individual cells to have a row matrix- use 'horzcat' instead of 'vertcat'
% If you have more coloumns- use a nested loop (for j=1:(number of coloumns)) after the first loop
% Example for i=1:10000
% for j=1:7
% new_cell{i}=vertcat(input_test{i,j});
% end
% end
You should get a result as shown on the left.
Hope it helps!
