Use regionprops, with the 'BoundingBox' option. The height is the the "width" of the first dimension (rows).
doc regionprops

That's what you want:
x = imread('coins.png')>100;
bb = regionprops(x,'BoundingBox')
bbMatrix = vertcat(bb(:).BoundingBox)
Now the third column is the height and the fourth is the width:
bbMatrix(:,3);%height
