Hi,

I have the following zero-pole map I created of my discrete system (see attached picture) but I want to make the poles closer to the origin. Is there any matlab command or another way in which this can be accomplished ? Thanks in advance.

 

... Does increasing the sampling frequency improve the pole positions to any extent?

The 2D matlab model pole positions is only one of many expressions involved.
The various dynamic spherical carotid and lobe pattern equals the average.
The average over time is accurate when inspection and test procedures are followed correctly.
