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

Next, if the fraction is nonproper, the direct term k is found using deconv, which performs polynomial long division
שבר חלקי
Numerically, the partial fraction expansion of a ratio of polynomials represents an ill-posed problem
For most textbook problems, k is 0 or a constant , p 1 are the poles, and k s is a polynomial in s
For repeated roots, resi2 computes the residues at the repeated root locations For most textbook problems, k s is 0 or a constant
