This GUI Solve Routh-Hurwitz Stability Criterion even if all element
of
row or first element of row is zero(0)

***************************new features***************************
1-find upper & lower limit of variable k(Gain) with Gain Finder tools
input equation(poly only) with k variable(for example: [1 0 5 0
k])
and set start & to & interval value

this show stable & boundary stable & unstable of each k value
default colors is:
stable:blue
boundary stable:green
unstable:red
you can change color voluntary

2- 8 bug fixed
******************************************************************

features:

1-Calculate exactly & display table of routh hurwitz in listbox
similar project cant solve accurate Routh-Hurwitz Stability
Criterion
for example this equation [1 1 3 3 3 2 1] have all element and
first
element zero simultaneity and i test any project and none solve
it

2-Determine where first element or all element is zero
graphically(change own row color voluntary)
similar project show this with text and confuse us

3-Factor s=0 roots
similar project dont have this feature . This gui factor s=0
roots
and solve Routh-Hurwitz Stability Criterion

4-display number of roots
this gui show number of
4-1-repeated roots on jw axis
4-2-left half plane roots
4-3-roots on jw axis
4-4-right half plane roots
4-5-number of center roots(s=0) that factor from input
equation
4-6-number of repeated center roots(s=0) that factor from
input equation

5-display result
5-1-unstable system
5-2-boundary stable system
5-3-stable system
note: s=0 roots that factor in input equation affect on result

6-Save table of Routh-Hurwitz
you can save table of Routh-Hurwitz in .mat format for future
usage

7-Color Scheme(beautiful)
you can change Color Scheme of this GUI

8-Solve Equation
you can obtain roots of input equation with this
note: s=0 roots that factor in input equation appear here

9-step & Impulse Response
you can plot step & impulse response by determine numerator
and denominator of transfer function .
default numerator is [1] and default denominator is poly
state of input equation
note: if number of zeros greater than poles then gui give error
message

10- Z_plane Diagram
you can see Z_plane(place of zeros & Poles) in the figure

11-Root Locus & Nyquist & Bode Diagram & singular value & nichols
you can see above diagram by determine numerator & denominator
of transfer function be similar to section 9

12-plot with LTI Viewer of MATLAB

13-support 2 Language
English & Farsi

14-Examples
this gui have 4 example for help you

15-Internal Help
this gui have internal help in html format

16-user freindly
everywhere you have mistake gui help you with messages

-------------------------------------------------------------
for run this gui open matlab and run Routh_Horwitz.m
