lpc (MathScript RT Module Function)
Owning Class: modeling and prediction
Requires: MathScript RT Module
Syntax
a = lpc(c)
a = lpc(c, n)
[a, b] = lpc(c)
[a, b] = lpc(c, n)
Description
Performs linear prediction coding.
Inputs
| Name | Description |
|---|---|
| c | Specifies the signal. c is a vector. |
| n | Specifies the order of the forward predictor for the signal c. The default is length(c) - 1. |
Outputs
| Name | Description |
|---|---|
| a | Returns the coefficients of the forward predictor. |
| b | Returns the variance of the prediction error. |
Examples
x = sin([0:0.1:10]);
n = 5;
y = lpc(x, n)
