For repeated roots, resi2 computes the residues at the repeated root locations Problem formulations making use of state-space or zero-pole representations are preferable

Next, if the fraction is nonproper, the direct term k is found using deconv, which performs polynomial long division

, r 1 are the residues, the values p m,
, p 1 are the poles, and k s is a polynomial in s The number of poles n is Algorithms residue first obtains the poles using roots
Numerically, the partial fraction expansion of a ratio of polynomials represents an ill-posed problem Finally, residue determines the residues by evaluating the polynomial with individual roots removed

If the denominator polynomial, a s , is near a polynomial with multiple roots, then small changes in the data, including roundoff errors, can result in arbitrarily large changes in the resulting poles and residues.
