rowsCI = rows(swtCI);
B = sort(PQMatx(:,3)); h=1; while h<=rowsCI; UB=(1-swtCI(h,1)); UBB=UB/2; UBBB=1-UBB; UBBBB = UBB*swtN; J = B(UBBBB,1); disp('Upper Bound for swtCI(i,1)'); disp(J); M = B((((1-swtCI(h,1))/2)*swtN),1); disp('Lower Bound for swtCI(i,1)'); disp(M); h=h+1; end;
this is my code. why cant matlab access and display negative numbers?

It is not about "access and display negative numbers", it is about the indices. Like you would try to access B(-1) or B(1.2).
Verify the values with in the B(<value>) brackets. When you put this in a script and not execute from the command line, you also get a line number where to debug.
