Details:
If A is a square matrix, hess(A) returns the wrong result. According to
"help hess" it should return the matrix converted to upper Hessenberg form.
But actually it returns the orthogonal matrix used to transform to upper
Hessenberg form.
For example:
A=rand(3)
hess(A)
gives P when it should give H. The command "[P H]=hess(A)" does work fine.
This should be really easy for you guys to fix.
