Please ask one question per thread and mark an answer as "accepted", when one problem is solved. Thanks.

The error message is clear, isn't it?
So either convert markerImage to the class of w, or the other way around:
markerImage = double(markerImage);
You define the variable markerImage and modify values in the undefined variable marker. Is this a typo?

img = imread('img.png');
img=rgb2gray(img);
img= im2uint8(img);
imshow(img);
marker = false(size(img));
marker(33:38,17:55) = true;
marker = im2uint8(marker);
figure,imshow(marker);
im = imreconstruct(marker,img);
figure, imshow(im);
These errors are resolved by using im2uint8
Error using ==> imreconstructmex Function imreconstruct expected MARKER and MASK to have the same class.
Error using ==> imreconstructmex MARKER pixels must be <= MASK pixels.
