[M, L] = jury(P,N)
This function gives the Jury's array from a numerical or SYMBOLIC polynomial and includes the two special cases: (1) the first element of the second row of a block is zero; (b) a row of zeros (when there are roots on unit circle or reciprocal roots like (r,1/r). The symbolic results can be used to solve inequalities and obtain the stability intervals of symbolic vaiables.

Computes the DFT of N real values and returns the first
N/2+1 DFT coefficients. N is an integral power of two.
It gets command line inputs from user about highest power and coefficients of characteristic equation and generates the table.
It also comments on the stability of the system.
Functions are described briefly below:
1) er_add: Add given tranfer functions.
2) er_blaschke: Perform desired frequency transformation of digital filter using Blaschke products.
3) er_conv: Multiply transfer functions.
The user has to provide the program the constants and parameters of the models using a dialog box. A pop-up menu and an update button allow the user to select the plot (Txy, activity coefficients and relative volatility).

Sym2Polys (by Paul Godfrey) cannot be run on MATLAB 7(Release 14). This function is an extension of the Matlab SYM2POLY and COEFFS functions in that it allows the coefficients to be symbolic and returns the full coefficient vector including the...
extcsv should make csv-like data feel like database tables with flexible selection and combination methods. Two separate modules provides plotting (with gnuplot) and data modelling (Least Square Method, linear with respect to the model coefficients)
It needs highest power and coefficients of the characteristic equation. It will also comment on stability of the system.
