To do it with only the means and standard deviations, you would have to write your own functions to calculate the one- and two-tailed t-probabilities, but fortunately with MATLAB that is not difficult:
N = 44;
v = 2*N-2;
tval = (Amean-Bmean) / sqrt((Asd^2+Bsd^2)/N);
tdist2T = @(t,v) (1-betainc(v/(v+t^2),v/2,0.5));
tdist1T = @(t,v) 1-(1-tdist2T(t,v))/2;
tprob = 1-[tdist2T(tval,v) tdist1T(tval,v)]
So your groups are significantly different at alpha = 0.05.
The functions are correct, but you may want to check my ‘v’ and ‘tval’ calculations to be certain it they are correct to your experimental design. If they are not, change them appropriately.
