chart
Nichols chart
Calling Sequence
chart([flags]) chart(gain [,flags]) chart(gain,phase [,flags])
Arguments
- gain
real vector ( gains (in DB))
- phase
real vector (phases (in degree))
- flags
a list of at most 4 flags list(sup [,leg [,cm [,cphi]]])
- sup
1 indicates superposition on the previous plot 0 no superposition is done
- leg
1 indicates that legends are drawn, o: no legends
- cm
color index for gain curves
- cphi
color index for phase curves
Description
plot the Nichols'chart: iso-gain and iso-phase contour of y/(1+y) in phase/gain plane
chart
may be used in cunjunction with
black.
The default values for gain
and
phase
are respectively :
[-12 -8 -6 -5 -4 -3 -2 -1.4 -1 -.5 0.25 0.5 0.7 1 1.4 2 2.3 3 4 5 6 8 12]
[-(1:10) , -(20:10:160)]
