My question  is are you some kind of dork who can't read a question?
I asked you what rk4 and svd are?
Don't get me angry... you'll be gone.

svd and rk4 software on the same page:

singular value decomposition:

numerical RK4 approximation

hi,
if you have any progrmme for svd to find the eigen
value of trajectory matrix and for some eigenvalue to
to construt the trajectory matrix again.

thanks

sorry i did not mentioned what do you mean by SVD and
SVD-singular value decomposition.
RK4 -ruge kutaa 4th order method/
i am extermely sorry.do not be angry.

It isn't polite to ignore
Mathematica has it's differential  form "built in",
so the question doesn't come up often.
I just have no idea what a
"singular value decomposition"
Maybe you can explain?
Have you had a course in numerical evaluation using computers?
And a differential equations mathematics course?
