[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). A similar program...
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.
This simulator creates a source to microphone impulse response in complex room environments. It's based on the image method by Steven Boll'79. You may select frequency dependent wall coefficients and orientation dependent sources. Please refer to...
rkn86 Integrates a special system of second order ordinary differential equations of the form d^2 y/dx^2 = f(x,y), y(x0)=y0, y'(x0)=y'0 using an effectivelly 8-stages Runge-Kutta-Nystrom pair of orders 8 and 6. The method advances...
Bouncing superball simulation with spin on arbitrary 2D surfaces. Simulates frictional collisions of a spinning ball against arbitrary surfaces. New surfaces can be added by the user to set up any scenario with multiple surfaces while the...
[a, b] = FOURIERexp2cossin(c) Calculate the cos (a) & sin (b) coefficients of the exponential Fourier coefficients (c) returned by fft(x)/size(x,1), while isreal(x) = true needs the unshifted coefficients as input
Fits an ellipsoid into a 3D set of points, allows some constraints, like orientation constraint and equal radii constraint. E.g., you can use it to fit a rugby ball, or a sphere. 'help ellipsoid_fit' says it all. Returns both the algebraic...
ButterParam - Fast parameters for a digital Butterworth filter
The calculation of filter parameters with BUTTER is expensive. Therefore ButterParam stores calculated parameters in a lookup-table to accelerate repeated calls with the...
This is a code for simulation of BPSK receiver using Direct Sequence Spread Spectrum. The performnace is evaluated in presence of AWGN and Rayleigh fading. Jakes' Model has been used to obtained coefficients for rayleigh fading.
This code solves the economic dispatch by quadratic programming.Monotonic quadratic Fuel cost equations with Bmn coefficients is considered this model.
MATLAB implementation of IGRF11 fortran code as function for calculating Earth mean magnetic field. Implementation has been modified to default to GPS reference coordinates with output B components North, East, and Vertical. Spherical harmonic...
This model uses Simulink and the Aerospace Blockset for modeling the airframe of a NASA HL-20 lifting body, which is a low-cost complement to the Space Shuttle orbiter. The Aerospace Blockset was used to rapidly assemble portions of the HL-20...
function c = generate_savitzkyGolay_coef1D(order,interval) INPUT: interval 1.must be a odd number; 2. smaller than size(vIN)
OUTPUT: c(ss,nn) Rows corresponds to coefficients for the target point, g_t, at different...
alculate the normalized partial energy sequence (NPES) for a given signal vector X.
If a particular transform is capable of capturing the key features of a signal in few coefficients, the NPES will approach unity for relatively... |
