Matrix dimensions must agree error

Hello, I have the following code and couldn't figure out what I am doing wrong. I am getting the following error,

Matrix dimensions must agree.

Error in trial_extracction (line 6)
if raw{k,1}=='Time, s'

[num,txt,raw] = xlsread('trial.xlsx');
  i=1;
  k=1;
  j=1;
  for k=1:1:(length(raw))
  if raw{k,1}=='Time, s'
      for j=k:1:(length(raw))
         if raw{j,1}=='<END DATA>'
             data=raw(k:(j-1),:);
             name=strcat(i,'_All_indent.xls');
               xlswrite(name, data, 1, A)
               i=i+1;
         end
      end
      end
  end

Looks like you want to do a string compare in these lines:

if strcmp(raw{k,1},'Time, s')
            :
       if strcmp(raw{j,1},'<END DATA>')
