Like C or Python, but unlike Matlab or R, when you write s = sT, s is a reference to the same array as sT, so if you change one, you change both – since they are the same array. If you want to make a copy, you can explicitly make a copy: s = copy(sT). If the matrix you are copying is all zeros, you're probably better off just make a new array of zeros than copying the other one.
