rc_to_lar (MathScript RT Module Function)
Owning Class: modeling and prediction
Requires: MathScript RT Module
Syntax
b = rc_to_lar(a)
Legacy Name: rc2lar
Description
Generates log area ratios from an input sequence of reflection coefficients. LabVIEW applies the inverse hyperbolic tangent to the elements in a and then multiplies the result by 2.
Inputs
| Name | Description |
|---|---|
| a | Specifies the reflection coefficients. a is a vector. |
Outputs
| Name | Description |
|---|---|
| b | Returns the log area ratios. b is a vector. length(b) equals length(a). |
Examples
a = [0.24, 0.15, 0.34, -0.1, 0.42];
b = rc_to_lar(a)
