                    SYMBOLIC MATRIX LIBRARY



 hello, here is a library wrote in internals
it works with list of list :


          { { a b }
            { c d } }

here is a summary of what it does

          DNN       determinamt

          ADJ       adjoint

          MNN       solve s linear system as 
                    2 : { d ... f }
                    1 : { { a ... b }{...}{ c ... d } }

          MNI       inverse

          CDN     constant multiplies the iddentity matrix k.I
                    2 : A
                    1 : 3

          ADD     +

          MLT       *

          SUB       -

          TRAN    transpose

          ATL       array to list [[][][]]

          LTA       list to array {{}{}{}}

          TOSTACK explode the list of list on the stack


have fun and email me for any comments and improvement
