Routh-Hurwitz stability criterion

Hurwitz criterion basically tells us how many poles are located in the Left-Hand Plane, Right-Hand P

Description

Routh-Hurwitz stability criterion identifies the conditions when the poles of a polynomial cross into the right
hand half plane and hence would be considered as unstable in control engineering.

good job and thank u for sharing

This Is The Best At The First!!!

[caio guimaraes]

Very good. And very simple to use. Good job!

[J. Palacio]

the Routh Hurwitz table returns by this algorithm is not the correct one and it uses a very big value of epsilon for one of the special cases.

[Dave Meissner]

confusing

accurate and works great. only issue is that for larger numbers, it uses scientific notation and as a result some precision is lost.

[Farzad Sagharchi]

@ J. Palacio
please explain more ! the result and algorithm both are correct.

@ Azeem A
numbers after precision isn't important , just changing sign of the first column in important.

very good but how I can operate m-file in command windows
please help me in this
thanks

The program is buggy and not accurate. Try [1 1 2 24] which is an example of Dorf control text book. Compare your result with this file:
http://www.mathworks.com/matlabcentral/fileexchange/25956-routh-hurwitz-stability-test
and compare the result.

thanks for the code but it's buggy as mentiond above , try the following vector [1 4 3 12]

[Np4e odhah]

sotty ,the code is working good

[Jack Lê]

thank you very much for sharing.

how can i get the criterion with a variable for example , [1 28 356 1952 5248 1000*kc]??
