Dear all,
I'm somewhat puzzled by what appears to be an inconsistency in polynomial coefficient order. Consider the polynomial A = 1 + 2*x + 3*x^2; If I want to create it using poly I must write A = poly([1 2 3], 'x', 'coeff'); But if I want to use it as the denominator of a filter (whose numerator we can call B) I must write y = filter(B, [3 2 1], x); Is there a reason for this?
