dct
A discrete cosine transform (DCT) expresses a finite sequence of data points in terms of a sum of cosine functions oscillating at different frequencies. DCTs are important to numerous applications in science and engineering, lossy compression of audio (e.g. MP3) and images (e.g. JPEG) (where small high-frequency components can be discarded), to spectral methods for the numerical solution of partial differential equations. The use of cosine rather than sine functions is critical for compression, since it turns out (as described below) that fewer cosine functions are needed to approximate a typical signal, whereas for differential equations the cosines express a particular choice of boundary conditions.

Sinus_Rhythm
This code loads the file Normal_Sinus Rhythm.ecg into matlab and has the
following outputs:
- plot of the voltage over the entire period
- plot of the voltage over 10 seconds
- plot of the residual over a 10 second period
- calculation of the average voltage, average residual, standard and deviation of voltage and the rms residual
- outputs the residuals as a single column of numbers to the text file assign1_out.txt"
