pruth - do you just have one file? If so, can you do this manually instead of using MATLAB?

read your file with
A = readtable(yourfile);
then follow this scheme:
A = [8 8 8 8 8 8 ; 7 7 7 7 7 7]; %% example data for your file
[r,c]=size(A);
A = num2cell(A);
B = cell(1,c);
B{1,1} = r;
C = [B ; A];
C is the output you are looking for
