shape description using FD fourier coeeficeients used for shape classification. the steps : 1 . find the indexes borders of edged image (input binary edged image see test for example) 2. sort the indexes so they in distance order 3. make complex vecotr x+jy 4 make fft 5 take first FD 6. make ifft currently the algorithm works for only symmetrical shapes !!! i promise to improve it for all the shapes link to theory : http://www.tsi.enst.fr/tsi/enseignement/re...rier/Part1.html http://www.tsi.enst.

Schedule Complex Shifts for Your Employees The Complex-25 Excel spreadsheet creates schedules where each employee can be assigned to a category (manager, cook, waiter, etc.), a location (Store A, Store B, etc.) and a time (10:30 AM - 4:30 PM) each day for up to a month. The spreadsheet can enforce age-related work rules and also keep track of your payroll budget based on employee wages and scheduled hours. Shift assignments are made from drop-down menus of qualified employees. The spreadsheet produces individual schedules and comes in sizes for 25, 50,100 and 200 employees.

The Complex Number Calculator Precision 45 application was designed to be a complex number calculator and works with complex numbers, but also can be used as a real number calculator, that is a scientific calculator. Button Mod stands for modulus and works on the same way as abs button. Button mod stands for modulo. Button Log stands for principal value of complex Log and is duplicated by button ln. Button log(z) works as Log(z)/ln(10) for complex z and as decimal logarithm for real z, although in Complex Analysis log denotes multi-valued function log(z)=Log(z)+2?ni.

Finding the Fourier transform of a rectangular pulse.. filtering the spectrum and regenerating the signal using the filtered spectrum is done... at the end Rayleigh theorem is proved by showing that the energy content of both time domain and frequency domain signals are equal.. your comments are required......

According to shannon theory it is possible to reconstruct a band limited signal from its Fourier components provided it is sampled sufficiently...just to demonstrate this, posting a small example based on that.

These are two M-files 'fourier1' and 'fourier2' The first is designed to demonstrate how triangular, rectangular, saw tooth, half wave and full wave rectified signals can be built from superposition of a predefined no of Fourier harmonic terms. It demonstrates how increasing the number of terms included in the summation will improve the signal shape. The second file is useful for analyzing actual audio signals connected to the PC line in port of the sound card. The out put of the program is plot showing all harmonic amplitudes contained in the signal.

This is a simulator of Complex ALU. For documentation http://www.dicecca.net/public/unina/Labora...o_Architettura/.

The script allows to easily fit predefined complex analytical laws exploiting the potentiality of Genetic Algorithms. The script receives as input the handle to the analytic laws to be fitted to data. Such law may depend on multiple variables and several parameters. This optimization approach may turn out to be particularly powerful when the number of variables and the number of parameters increases a lot.

One cannot interpolate a complex number in the form of Real + j*imaginary. The only way to do interpolation is on the complex representation of an amplitude + phase. But sometimes the phase is not continuous, and given in the modulo(2*pi) representation (such as the result from the "FFT" function). Using "unwrap" function does not always manage to restore the phase to be continuous, thus interpolation in the Fourier plane is probably the only answer. This function works on a single or 2 dimensional arrays.
