dsp.VectorQuantizerDecoder
(Removed) Vector quantizer codeword for given index value
dsp.VectorQuantizerDecoder
has been removed.
Description
The VectorQuantizerDecoder
object associates each input
index value with a codeword, a column vector of quantized output values defined in the
Codebook
property. Each column of the Codebook
property is a codeword. When you input multiple index values into this object, the object
outputs a matrix of quantized output vectors. This matrix is created by horizontally
concatenating the codeword vectors that correspond to each index value.
You can select to enter the code book values via the Codebook
property or as an input to the object.
To obtain the vector quantizer codeword for a given index value:
Create the
dsp.VectorQuantizerDecoder
object and set its properties.Call the object with arguments, as if it were a function.

Creation
Description
creates a
vector quantizer decoder System object™, vqdec
= dsp.VectorQuantizerDecodervqdec
, that returns a vector quantizer codeword
corresponding to a given, zero-based index value.
returns a vector quantizer decoder, vqdec
= dsp.VectorQuantizerDecoder(Name,Value
)vqdec
, with each specified
property set to the specified value.

Object Functions
To use an object function, specify the
System object as the first input argument. For
example, to release system resources of a System object named obj
, use
this syntax:
release(obj)
Examples
Algorithms
This object implements the algorithm, inputs, and outputs described on the Vector Quantizer Decoder block reference page. The object properties correspond to the block parameters, except:
There is no object property that directly corresponds to the Action for out of range index value block parameter. The object sets any index values less than
0
to0
and any index values greater than or equal to N to N-1.
