File Information
Description

Features:

1-Calculate Exactly & Display Table Of Routh Hurwitz In Listbox
      Similar Project Can't 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 Don't 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-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

7-Save Table Of Routh-Hurwitz
      You Can Save Table Of Routh-Hurwitz In .mat Format For Future Usage

8-Color Scheme(Beautiful)
      You Can Change Color Scheme Of This GUI

9-Solve Equation
      You Can Obtain Roots Of Input Equation With This
Note: s=0 Roots That Factor In Input Equation Appear Here

10-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

11- Z_plane Diagram
      You Can See Z_plane(Place Of Zeros & Poles) In The Figure

12-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

13-Plot With LTI Viewer Of MATLAB

14-Support 2 Language
      English & Farsi

15-Examples
      This Gui Have 4 Example For Help You

16-Internal Help
      This Gui Have Internal Help In Html Format

17-User Friendly
      Everywhere You Have Mistake Gui Help You With Messages
