Extract zeros and poles from the zepo format.
Syntax
[ze,po] = getzp(zepo)
[ze,po] = getzp(zepo,ku,ky)
Description
The basic use of getzp is to extract the poles and zeros of the coded format that th2zp results in. zepo contains this information and is typically the output of th2zp. ku contains the input number (just one) and ky the output number. The noise source number k is here counted as input number -k.
ze contains the zeros and po the poles of the dynamics associated with input number ku and output number ky. The default values of ku and ky are both 1.
Note that for the noise dynamics, zepo normally just contains information about the zeros and poles from noise source k to output number k, (no cross terms). To extract this information enter
[ze,po] = getzp(zepo,0,k)
