Merge zero-pole information from different models.
Syntax
zepo = zpform(zepo1,zepo2,...,ku)
Description
The zeros and poles in zepo1, zepo2, ... from different models are merged into one matrix to be used by zpplot. zepo1, zepo2, ... have the format as produced by th2zp. ku is an optional row vector containing the input numbers to be picked out when forming zepo. The default value is ku is equal to all inputs present in zepo1, zepo2, ... A maximum of five input arguments to
zpform is possible.
Examples
The statement
zpplot(zpform(zpbj2,zpbj4,zpax2,zpax4,0))
compares the noise characteristics from four different models.
