Inverse of a MatrixI have three new pages for you all to look at (and comment on): "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #2 20110624 10:57:13
Re: Inverse of a MatrixHi MIF; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #3 20110624 11:58:33
Re: Inverse of a MatrixI think perhaps I should, as it is the more common form. But it leads people to think that the heights (number of rows) are "naturally" matched ... if you see what I mean. When you approach it the other way then you need to think more about sizes of rows and columns. "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M.

Re: Inverse of a MatrixThat is okay with me. Then keep it the way that is more didactic. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
