M-file |
Date | Change |
|---|---|---|
| airgnotes.m | 18-Sept-99 | Initializes vectors of note values
and types for generating "Air on a G-String." |
| airgshort.m | 18-Sept-99 | Initializes vectors of note values
and types for first two measures of "Air on a G-String." |
| dirich.m | 7-Oct-99 | Substitute for MATLAB function
called diric.m Calculates the Dirichlet function |
| dtft.m | 1-Feb-02 | Discrete-Time Fourier Transform |
| dtmfchck.m | 5-Dec-02 | Needed for DTMF Lab |

| firfilt.m | 10-Oct-01 |
This version will not fail when the xx input is a matrix;
instead, it will filter down each column of the matrix. Previous update for a bug fix was 23-April-01. |
| freekz.m | 17-Oct-02 | Substitute for MATLAB function
called freqz.m Calculates the frequency response of a digital filter |
| hammfilt.m | 15-Nov-01 | FIR filter design with Hamming window |
| hamming.m | 28-Oct-98 | Just in case hamming.m is needed elsewhere |
| hanning.m | 28-Oct-98 | von Hann window might be needed in spectgr.m |
| image2bmp.m | 19-Feb-00 | Convert image to a bit map graphics file |
| j_notes.m | Feb-99 | Initializes vectors of note values
and durations for generating "Jesu, Joy of Man's Desiring." |
