Codes

These are some simple and useful functions I wrote on MATLAB for data analysis:

  • powerd: Computes the average power of an n-dimensional signal;
  • energyd: Computes the energy of an n-dimensional signal;
  • errord: Computes the absolute difference between two signals;
  • msed: Computes the mean-squared error between two signals;
  • ser: Computes the signal-to-error ratio between two signals.
