Class Summary

Class	Description
ArrayToSequence	This actor reads an array at the input and writes the array elements as a sequence to the output.
Autocorrelation	This actor calculates the autocorrelation of a sequence of input tokens.
BitsToInt	This actor converts a sequence of BooleanTokens into a single IntToken.
BootstrapSampleDelay	Record an initial token and then output that initial token during initialize(), then pass through.
Chop	This actor reads a sequence of input tokens of any type, and writes a sequence of tokens constructed from the input sequence (possibly supplemented with zeros).
CountTrues	Read the given number of input booleans and output the number that are true.
DelayLine	This actor reads tokens from its input port, and for each token read outputs an array that contains the current token as the first token, followed by some number of previously read tokens.
DotProduct	Compute the dot product of two arrays or matrices.
DoubleToMatrix	Deprecated. Use SequenceToMatrix instead.
DownSample	This actor downsamples an input stream by an integer factor by removing tokens.
FFT	This actor calculates the Fast Fourier Transform of a sequence of complex inputs.
FIR	This actor implements a type polymorphic finite-impulse response filter with multirate capability.
IFFT	This actor calculates the inverse FFT of a complex input array.
IntToBits	This actor converts an IntToken into a sequence of Boolean tokens.
LineCoder	A line coder, which converts a sequence of booleans into symbols.
LMSAdaptive	An adaptive filter using the Least-Mean Square (LMS) algorithm, also known as the stochastic gradient algorithm.
MatrixJoin	This actor joins matrices into a single matrix by tiling.
MatrixSplit	This actor splits an input matrix into a sequence of matrices.
MatrixToDouble	Deprecated. Use MatrixToSequence instead.
MatrixToSequence	This actor unbundles a matrix into a sequence of output tokens.
RaisedCosine	This actor implements an FIR filter with a raised cosine or square-root raised cosine frequency response.
Repeat	An actor that repeats a block of input tokens the specified number of times on the output.
SampleDelay	This actor outputs a set of initial tokens during the initialize() method, and subsequently passes the input tokens to the output.
SDFConverter	This actor is a base class for SDF converters.
SDFTransformer	This is an abstract base class for actors that transform an input stream into an output stream.
SequenceToArray	This actor bundles a specified number of input tokens into a single array and broadcasts the resulting array on all output channels.
SequenceToMatrix	This actor bundles a specified number of input tokens into a matrix.
UpSample	This actor upsamples an input stream by an integer factor by inserting tokens with value zero.
VariableFIR	This actor implements a type polymorphic finite-impulse response filter with multirate capability, where the impulse response of the filter is provided by an input.
VariableLattice	This actor implements an FIR filter with a lattice structure where the reflection coefficients are supplied at an input port.
VariableRecursiveLattice	This actor implements a recursive (all-pole) filter with a lattice structure where the reflection coefficients are supplied at an input port.
