Difficulty with createLine

[Thomas D. Dean]

I have two scripts that create lines, using the same data, but different 
calls and I get different lines when I think I should be getting the 
same line.

The first set of data comes from a complicated calculation.

octave:1027> relTgtPosit
relTgtPosit =

   95.0000   16.0000
   80.2279   -3.8953
   65.4558  -23.7906
   53.4611  -31.3488
   29.4717  -46.4653
    5.4823  -61.5818
relTgtLeg = 
createLine([relTgtPosit(1,:),relTgtPosit(3,:);relTgtPosit(3,:),relTgtPosit(6,:)])

The second set of data comes from direct assignment

T1 = [95.0000   16.0000]
T2 = [80.2279   -3.8953]
T3 = [65.4558  -23.7906]
lineT = createLine(T1,T3);

figure; hold on; axis([0 120 -80 20]);
grid
drawLine(relTgtLeg(1,:), 'color', 'b')
drawLine(lineT, 'color', 'c')
hold off

I think the two lines, relTgtLeg(1,:) and lineT should be the same.

What am I doing wrong?
