Solve given (noninteger) linear programming problem using the Simplex Algorithm (Simplex Method).
What we mean here by "linear programming problem" (or LP problem, for short) can be formulated as:
\[\mbox{Maximize } c\cdot x\\ \mbox{Subject to:}\\ Ax\leq b\\ x\geq 0\]
Where \(c\) is fixed
1
by
n
rowvector, \(A\) is fixed
m
by
n
matrix, \(b\) is fixed
m
by
1
column vector and \(x\) is an arbitrary
n
by
1
column vector, which satisfies the constraints.
Simplex algorithm is one of many algorithms that are designed to handle this sort of problems efficiently. Although it is not optimal in theoretical sense (there exist algorithms that can solve any problem written as above in polynomial time, while simplex method degenerates to exponential time for some special cases), it is wellstudied, easy to implement and is shown to work well for reallife purposes.
The particular implementation is taken almost verbatim from Introduction to Algorithms, third edition by T. H. Cormen, C. E. Leiserson, R. L. Rivest and Clifford Stein. In particular, the Bland's rule http://en.wikipedia.org/wiki/Bland%27s_rule is used to prevent cycling.
Func  This rowvector corresponds to \(c\) in the LP problem formulation (see above). It should contain 32 or 64bit floating point numbers. As a convenience, columnvector may be also submitted, in the latter case it is understood to correspond to \(c^T\). 
Constr 
m
by
n+1
matrix, whose rightmost column corresponds to \(b\) in formulation above and the remaining to \(A\). It should contain 32 or 64bit floating point numbers.

z  The solution will be returned here as a columnvector  it corresponds to \(c\) in the formulation above. It will contain 64bit floating point numbers.
