How to calculate pitch for voiced speech signals?
[Material from duplicate question]
- I need how to calculate the pitch for voiced speech signal?
- How to calculate the LP residual signal? The equation is
e_n = x_n - sum_{k=1}^p a_k x_{n-k}.

@Walter, that is much nicer than just sticking a doit4me tag or something like it on the question.

To calculate the LP residual, use the lpc function in the Signal Processing Toolbox. To estimate the pitch of an audio signal, use the pitch function in Audio System Toolbox.
FYI: If you're thinking to use the residual to calculate the pitch, one of the algorithms available from the pitch function is the Summation of Residual Harmonics*, which does just that. So it could be a good place to start.
