emat = cell([],1) ;
% INPUT OF INITIAL MATERIAL DISTRIBUTION
% ONLY in 1st ITERATION
if (a==1)
fid = fopen('emat_initial.txt','r');
temp = fscanf(fid,'%g',[1 inf]);
emat{1} = temp';
fclose(fid);
end
The problem is because of size temp. Know the isze of temp and initialize emat. If size is not know save them into a cell array as shown in the code.
