2 way ttest in matlab not showing results

T = [SJ SJ SJ CM CM SJW; CM SJW CMW SJW CMW CMW]';         
% Creates a matrix with the jump type numbers, so that each type is compared to the other

 for ii=1:6
    [Ttestmjh(ii,1) Ttestmjh(ii,2)]  = ttest2((jhmn(:,T(ii,1))),(jhmn(:,T(ii,2))));  
% Runs a 2 tailed t-test on the mean jump height for each jump type
    [Ttestsdjh(ii,1) Ttestsdjh(ii,2)] = ttest2((sdjh(:,T(ii,1))),(sdjh(:,T(ii,2)))); 
% Runs a 2 tailed t-test on the sdev jump height for each jump type
 end

my ttest runs but produces no actual data in the matrix of Ttestmjh and Ttestsdjh that I had made at the top of my code.

the T value produces the right matrix.
