The present submission is a set of four Matlab functions that provides a generation of:
1) Pink (flicker) noise - power spectral density slope -3 dB/oct., -10 dB/dec.
2) Red (Brownian) noise - power spectral density slope -6 dB/oct., -20 dB/dec.
3) Blue noise - power spectral density slope +3 dB/oct., +10 dB/dec.
4) Violet (purple) noise - power spectral density slope +6 dB/oct., +20 dB/dec.
A few examples are given to clarify the usage of the functions. For convenience, the input and output arguments are given in the beginning of each function. The generated noise signal has a unity standard deviation and zero mean value.
The code is based on the theory described in:
