Constructing nested for loop - outer loop query, help?

I'm using a pair of for loops to make calculations of some angles due to a change in 2 variables. Inner loop is working but I would like to compute 5 additional sets (6 total sets) of these 11 calculations but this time change the variable h by doubling it i.e 2*h (starting from h=0.5985) within the outer loop.

Do I have to create a new dummy variable to store the increase in the loop each time? For example, i've used 'increment' in the second last line even though this is actually a value of h. Can I recall h and just say h(j) = h*(2*j)..etc

h=0.5985   

for J = 1:6

     for K  = 1:11

     TreeLengthTest(K) = TreeLengthRHS + (2*K*a);
     TreeLengthLHS = 75 - TreeLengthTest(K);

     % Distances, Azimuth and Altitude Angles

     AngleBx(K) = atand(TreeLengthLHS/GroundDistance);
     AngleCx(K) = atand(TreeLengthTest(K)/GroundDistance); %wasTreeLengthRHS
     DistanceAx(K) = GroundDistance/cosd(SouthAngle);
     DistanceBx(K) = GroundDistance/cosd(AngleBx(K));
     DistanceCx(K) = GroundDistance/cosd(AngleCx(K));
     AltAngleA(K) = atand(POI/DistanceAx(K));
     AltAngleB(K) = atand(POI/DistanceBx(K));
     AltAngleC(K) = atand(POI/DistanceCx(K));

     AzimuthA = 0;
     AzimuthB = (-AngleBx)-SouthAngle;
     AzimuthC = AngleCx-SouthAngle;

     end

end

[Walter Roberson]

for K = 1  : 6
  increment = h * 2^(K-1);
  ......
  TreeLengthRHS(K) = ....
end

Could you possibly add this syntax Into the code? I tried this but kept getting errors and crashed my system.

Also, I only want h to double once it has completed a set of 11 calculations so that it can then use the new value of h to calculate 11 more. Thanks.
