Singular matrix ?

    singular matrix ????

    Hi, guys,

    < in matlab >
    what should i do if i want to get the inverse matrix but it's a singular one? can i just add a very small identity matrix like 0.00005 on the diagnol? will it change the result?


    w0 = S\meandiff

    is that the same as

    w0 = ( S+0.00005*eye( size( S ) ) )\meandiff

    Usually if you get a singular matrix, you screwed up somewhere before the inverting step.
