GUI for Routh-Hurwitz Criterion

Input commands in the edit text, and it will compute and display the Routh-Hurwitz array.

There are 5 M-files : Routh_Gui.m, OnOk.m, routh.m, disp_result.m, funct.m. And Routh_Gui.m is used for creating the interface(using uicontrol,uipanel), OnOk.m is the callback function of pushbutton 'OK'. Based on the code written by Rivera-Santos, Edmundo J. , routh.m is modified a little to compute the Routh-Hurwitz array. File disp_result.m is used to diaplay the Routh-Hurwitz array and some other information on the GUI, and funct.m is to save the command that typed in the Edit text. Type 'Routh_Gui' in the command window to run the program.
