dsort

Sort discrete-time poles by magnitude.

Syntax

• s = dsort(p)
• [s, ndx] = dsort(p)

Input argument

• p - p: a vector

Output argument

• s - sorted vector by magnitude.

Description

dsort arranges the discrete-time poles within the vector p in a descending order based on their magnitude, with unstable poles taking precedence at the beginning of the sorted list.

Example

p = [-2.410 + 5.573i;
-2.410 - 5.573i;
1.503;
-0.972;
-2.590];
[s, ndx] = dsort(p)
