<font face="Courier New">Dear all,<br>
<br>
I'm somewhat puzzled by what appears to be an inconsistency in
polynomial coefficient order.<br>
<br>
Consider the polynomial<br>
<br>
A = 1 + 2*x + 3*x^2;<br>
<br>
If I want to create it using poly I must write<br>
<br>
A</font> = poly([1 2 3], 'x',
'coeff'<!--[if gte mso 9]><xml>

<br>
But if I want to use it as the denominator of a filter (whose
numerator we can call B) I must write<br>
<br>
y = filter(B, [3 2 1], x);<br>
<br>
Is there a reason for this?<br>
<br>
