If you have the Image Processing Toolbox, this is how you do it:
% Create sample data
A = [0,0,0,0,1,1,1,1,1,0,0,0,0,0,1,1,1,0,0,0,1,1,1,1,1,1,0,0,1,1,0,0,1,1]
% Label the 0's.
labeled0 = bwlabel(~A)
% Count the number of 0's.
measurements0 = regionprops(labeled0, 'Area');
% Label the 1's.
labeled1 = bwlabel(A)
% Count the number of 1's.
measurements1 = regionprops(labeled1, 'Area');
% Stitch together into a single matrix.
zeroAreas = [measurements0.Area]
onesAreas = [measurements1.Area]
bothAreas = [zeroAreas;onesAreas]
% Reshape into a row vector.
finalOutput = bothAreas(:)'
