Unable to perform assignment because the indices on the left side are not compatible with the size of the right side.

% 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

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.
