how to find scaling,rotate,translate values of affine transform?

I have 2 triangle .I want to find translate, scale, rotation values between them in matlab. I use affine transform for it .my code is:

A.x=[309;367;295];            
A.y=[292;259;277];   
Aprim.x=[267;211;265]; 
Aprim.y=[301;222;325]; 
A_xprim(1:3,1)= transpose(Aprim.x(1,1:3));
A_yprim(1:3,1)=transpose(Aprim.y(1,1:3));  
 Ax(1:3,1)= transpose(A.x(1,1:3));
 Ay(1:3,1)=transpose(A.y(1,1:3));
tform = maketform('affine',[A_xprim(1:3,1) A_yprim(1:3,1)],[ Ax(1:3,1)  Ay(1:3,1)]);

but my output are: tform.Tdata.T=[-0.196 1.120 0;-0.716 0.200 0;498.66 -56.004 1] tform.Tdata.Tinv=[0.262 -1.467 0;0.938 -0.257 0;-78.272 717.215 1]

which elements are scaling,translate,rotate value?
