function [fl re]=lines(aa)
%Divide text in lines.
aa=clip(aa);
r=size(aa,1);
for s=1:r
if sum(aa(s,:))==0
nm=aa(1:s-1,1:end);%First line matrix
rm=aa(s:end,1:end);%Remain line matrix
fl=~clip(~nm);
re=~clip(~rm);
%*-*-*Uncomment lines below to see the result*-*-*-*-
subplot(2,1,1);imshow(fl);
subplot(2,1,2);imshow(re);
break
else
fl=~aa;%Only one line.
re=[];
end
end

Just as the error says... "aa" is a logical, and you are calling a function "clip" with it. But matlab was not able to find any function which matches this format.

You need to visit http://www.mathworks.com/matlabcentral/fileexchange/49832-a-simple-system-for-automatic-test-processing-and-exam-scoring and download the .zip there. Unzip it into a convenient directory that is not underneath your MATLAB installation. Use the MATLAB pathtool to add that directory to your MATLAB path and remember to tell pathtool to "save" the path. After that you will be able to call upon clip.
