Hi, while converting a Matlab source, I encountered the poly(r) function. The Matlab documentation, says : " p = poly(r) where r isa vector returns a row vector whose elements are the coefficientsof the polynomial whose roots are the elements of r ." ( http://www.mathworks.it/help/techdoc/ref/poly.html ) I tried to find a similar function in Apache Math, but I could only find the opposite: build a polynomial from coefficients, and then find the roots. How can I implement the Matlab poly functions using Apache Math? I need it only in the second form, passing a vector of roots, not a matrix. Thanx for any help, Gabriele.
