**colored_noise_test**,
a C++ code which
calls colored_noise() to
generate sequences that simulate
1/f^alpha power law noise. This includes white noise (alpha = 0),
pink noise (alpha = 1) and brown noise or Brownian motion (alpha = 2),
but also values of alpha between 0 and 2.

colored_noise, a C++ code which generates samples of colored noise obeying a 1/f^alpha power law.

- colored_noise_test.cpp a sample calling program.
- colored_noise_test.sh a sample calling program.
- colored_noise_test.txt, the output file.

**ALPHA** is a sequence of 9 sets of data, for ALPHA = 0.00 to ALPHA
= 2.00, each time computing a sequence of 128 values, and using the
same sequence of random numbers. This makes the effect of ALPHA
very clear.
