Thanks a lot. With your help, I have now found these pages in the documentation (looking for 'linear algebra', and then chosing the 'Linear algebra in Mathematica' tutorial). I have however no 'Virtual book' option in the Help (I am using version 6.0.1.0), which is a pity. Is there another way to access the book as a whole with version 6 ?
