Lec 10 MIT 18.085 Computational Science and Engineering I
to go on lecture 10 so let me say what lecture 10 is about it's going to bring back it won't be entirely about uh what we did before but it's going to bring back these matrices you remember this was K4 in the from the first lecture with twos all the way along the diagonal and then T4 uh the one with a change at the top uh change that two to a one and then I don't know if I gave this one a name this is the one that where the changes down at the bottom and uh so it's really just it's very very closely related to this guy just the changes it's h maybe is for hanging because this was the the change came at the bottom when we had those Springs and masses hanging in a in a line where the change came at the Top If the top boundary was free so this is this is I'll use so this is fixed fixed fixed at both ends and this one is free at the top and fixed at the bottom and this one corresponds to fixed at the top and free at the bottom okay okay so one ...
