Calculating a withdrawl plan? For Loop - In an assignment A(I) = B, the number of elements in B and I must be the same. -

I try to calculate a withdrawl plan from a portfolio.

InitVal = 100
R_until_85 = 0.35
iNumObs = 10
iNumSim = 100

mRetRisky = [0,0194563288529693  -0,0566781000933427;
             0,0492829304809960  -0,0768978197776796]

%Preallokation
mSimPrice=NaN(iNumObs,iNumSim);

this is the result i want to get:

vInitVal = repmat(InitVal,1,size(mRetRisky,2));
    vR_until_85 = repmat(R_until_85,1,size(mRetRisky,2));
    %    vInitVal_1 = (vInitVal-vR_until_85) .* exp(mRetRisky(1,:));
    %    vInitVal_2 = (vInitVal_1-vR_until_85) .* exp(mRetRisky(2,:));
    %    vInitVal_3 = (vInitVal_2-vR_until_85) .* exp(mRetRisky(3,:));

but the Loop isn't working, where is the difference?:

   for i=1:iNumObs;
      vInitVal = (vInitVal-R_until_85) .* exp(mRetRisky(i,:));
   mSimPrice(i) = vInitVal;  
   end

Cheers Thanks!!

mSimPrice(:,:,i) = vInitVal;
