Software Listing: Frequency Analysis

Frequency analysis allows the calculation of the natural (resonant) frequencies of the design and related forms of vibrations. It is useful in carrying out checks for the resonant frequencies in the working frequency range and optimizing the design in such a way as to prevent the emergence of resonances. So developer can improve the reliability and efficiency of the design. In the parameters of frequency analysis determined the number of natural frequencies to be determined. The system may be not fixed (free in space). Calculation of resonant frequencies takes into account the forces acting on the structure (eg, gravity).

LTFAT, short for Linear Time / Frequency Toolbox is designed to be a Matlab / Octave toolbox for executing time-frequency analysis.

It is intended both as an educational and computational tool. The toolbox provides the basic Gabor, Wilson and MDCT transform along with routines for constructing windows (filter prototypes) and routines for manipulating coefficients.

This PHP script simply takes the contents of a webpage, pasted onto a form, and by running a simple frequency analysis on the words in the page (excluding common words), it produces a list of the most common 1 word, 2 word and 3 word strings within the page. From this it builds a suitable keyword string which can be used within the meta tags of the originating page. It can often provide ideas for keywords which may have overlooked the author the page, who probably knows the theme too well..

This function uses frequency analysis to attack and decode messages encoded using a /substitution cipher/ which exchanges each letter of the alphabet for another. Unlike the famous "Caesar Shift" cipher, which "shifts" the letters of the alphabet along by a certain amount, giving just 26 possible ciphers, this has no specific order, giving 26! possibilities. The function is very unlikely to work first time but, depending of the length of the text, highly likely to get the letters "T" and "E" correct. From here the user may spot an error in the decoding, such as "TQE" which is obviously "THE", and the function offers them the chance to swap the offending letters as often as is required.
