simplex tableau and Matlab

Simplex tableau is used to find the best strategy for a linear system.

There are various subfunctions but the
functions in the zip file, but the main function is called simplexTab.

given the simplex tableau 'a' and specifying the number of free variables.
just a sample run:
a=[7 3 9 1 0 0 0 1;8 5 4 0 1 0 0 1;6 9 5 0 0 1 0 1; -1 -1 -1 0 0 0 1 0];
numFreeVar=3;
c=optiDual(a,numFreeVar);

c =

Columns 1 through 4

0 0 1 42/253
1 0 0 -1/23
0 1 0 -16/253
0 0 0 15/253

Columns 5 through 8

-45/253 1/23 0 8/253
6/23 -3/23 0 2/23
-19/253 4/23 0 9/253
2/253 2/23 1 39/253

v=1/(39/253)
X=[8/253 2/23 9/253];

col strategy=vX;

v=1/(39/253)
Y=[15/253 2/253 2/23];
row strategy=vY;
