Making Additions to MAYBE-NC00

When making additions to NCAlgebra through the use of MAYBE-NC00 one should put at least 4 files in the directory /home/toal/MAYBE-NC00.

For example let's assume that the project is NCX1Project. Associated with NCX1Project one should find the following files in MAYBE-NC00

  • NCX1Project.m --- the main file which contains the main routines.
  • NCX1Project.NCTest --- the file which tests the functions provided in NCX1Project.m. Look at another *.NCTest before creating this one.
  • NCX1Project.nb --- A notebook which demonstrates the use of the functions provided in NCX1Project.m.

    • NCX1Project.tex --- The documentation for the functions provided in NCX1Project.m.

    Summer 2001

    PSEUDO INVERSE STUFF:
    Here is the paper on PseudoInverses (.dvi) (.tex) .
    See below for runs that contributed ( and some more ) to the above paper.
    PseudoInverse of A has a finite GB. (.dvi) (.tex)
    PseudoInverse of A,B, and A + B has a finite GB. (.dvi) (.tex)
    PseudoInverse of A,B, and AB does NOT have a finite GB.
    dvi: (3 iters) (4 iters) (5 iters)
    tex: (3 iters) (4 iters) (5 iters)
    PseudoInverse of A,B, and A**Pinv[A]+B**Pinv[B] has a finite GB. (.dvi) (.tex)
    PseudoInverse of A,B, and A**Pinv[A] + Pinv[B]**B has a finite GB. (.dvi) (.tex)
    PseudoInverse of A,B, and (1-Pinv[B]**B)**A**Pinv[A] has a finite GB. (.dvi) (.tex)
    PseudoInverse of A,B, and (1-Pinv[B]**B)**A**Pinv[A] AND A**Pinv[A]+Pinv[B]**B has a finite GB. (.dvi) (.tex)
    Here is the mathematica file with all of the previous runs.


    PSEUDOINVERSE OF A COLUMN MATRIX
    Here is the mathematica file for the pseudoinverse of a column matrix.
    Here is the (.dvi) (.tex) file for its output.
    Note that we are solving for the pseudoinverse of a 2x1 matrix with entries a and b where the pseudoinverse is a 1x2 matrix with entries c and d. It turns out that c = Pinv[tp[a]**a+tp[b]**b]**tp[a] and d = Pinv[tp[a]**a+tp[b]**b]**tp[b].

    EP PROBLEM
    Here is a link to the EPProblem page.

    Summer 2000

    Everybody helps with NCAlgebra testing as much as possible.
    Set your init.m file correctly.
    Juan will help.
    Always Use 2nd Floor Lab.
    Juan there on certain afternoons.

    Everybody criticses  NCAlgebra document as much as possible.
     
     

    camino@ucsd.edu

    Supervising-
    Mma Software to do:  LDU  , Hessian Convexity check
    we want a good flexible package.

    Experiments on systems problems (juan, bob, mauricio suggest some).
     

    Doing with Maurico some nice engineering notebooks.

    Supervisor of the breakers (dan and josh) is MAURICIO.
     Mauricio C. de Oliveira <mauricio@mechanics.ucsd.edu>

    dan and josh - dan and josh should report what they
    have done to him regularly.
