Attempted to access sorted_evalue(1); index out of bounds because numel(sorted_evalue)=0. smallest_ev1p = 0.01 * sorted_evalue(1); % to obtain the effective eigen values

[sorted_evalue, index] = sort( evalue );
sorted_evalue = flipud( sorted_evalue );
index = flipud( index );
evector( :, 1:nof ) = evector ( :, index );
smallest_ev1alue = (1/100) * sorted_evalue(0);
for i = 1:nof
if (sorted_evalue(i) < smallest_evalue)
break;
end
end
index = i+1;
evector = evector( :, 1:index );

Your code fails if evalue is empty at the start of your code. You assume that it is not empty without testing it.
Note: you may wish to consider using sort with 'descending' flag instead of flipud() on the results. You will also need to fix the problem with evalue being empty, but it will make the rest of your code more simple.
