lsf_to_poly (MathScript RT Module Function)
Owning Class: modeling and prediction
Requires: MathScript RT Module
Syntax
b = lsf_to_poly(a)
Legacy Name: lsf2poly
Description
Generates a prediction polynomial from line spectral frequencies.
Inputs
| Name | Description |
|---|---|
| a | Specifies the line spectral frequencies. a is a vector. All elements in a must be between 0 and pi. |
Outputs
| Name | Description |
|---|---|
| b | Returns the prediction polynomial. b is a vector. length(b) equals length(a) + 1. The first element in b is always 1. |
Examples
a = [0.02, 0.08, 0.3, 0.5];
b = lsf_to_poly(a)
