tform function in matlab

Could anyone please help me to understand the value of tform matrix generated in this code? I got the tform matrix value as

tform.T = 

    0.9280   -0.0019          0
    0.0019    0.9280          0
   -90.8909  -31.3300    1.0000

I want to get the value of rotation matrix (2X2) and translation parameters tx and ty. Below is the code:

Image1 = imread('lineseg_left.jpg');
figure(9), imshow(Image1), title('Original image');

[xFixed, yFixed] = getpts;
fixedPoints(:,1) = xFixed; 
fixedPoints(:,2) = yFixed; 

% Choose points interactively in the displayed image using the mouse.
% Double-click to complete your selection. When you are done, getpts
% returns the position of your points.

Image2 = imread('lineseg_right.jpg');
figure(10), imshow(Image2),title('distorted image');

[xMoving, yMoving] = getpts;
movingPoints(:,1) = xMoving; 
movingPoints(:,2) = yMoving; figure(11),imshowpair(Image1,Image2,'montage'),title('Original and distorted image');
%Nonreflective similarity transformations may include a rotation, a scale
% and a translation. Shapes and angles are preserved. Parallel lines remain
% parallel. straight lines remain straight.
% Recover the transformation
tform = fitgeotrans(movingPoints,fixedPoints,'NonreflectiveSimilarity');
% Use the tform estimate to resample the rotated imageto register it with
% the fixed image. The regions of color(green and magenta)in the false
% color overlay image indicate error inthe registration. This eror come
% form a lack of precise correspondance in the control points.
Image2Registered = imwarp(Image2,tform,'OutputView',imref2d(size(Image1)));
figure(12)
imshowpair(Image1,Image2Registered),title('Original image and Registered image');
tform.T %show the transform

Here is a Matlab document that explains each element in the tform matrix.
