Constructor & Destructor Documentation

AnalogFilter::AnalogFilter (  unsigned int    kernel_length = 1 )

Constructs a new analog filter. Parameters: kernel_length  The length of the filter kernel.

AnalogFilter::~AnalogFilter (  void    )  [virtual]

Frees the memory.

Member Function Documentation

void AnalogFilter::addChannel (    )  [virtual]

Adds one input channel.

virtual void AnalogFilter::createKernel (  unsigned int    n )  [pure virtual]

Calculates a new filter kernel for the given number of data points. Parameters: n  Number of data points to filter. Implemented in GaussianAnalogFilter, TriangularAnalogFilter, and UserAnalogFilter.

int AnalogFilter::filter (  const double *    r, double *    x, int *    indices = 0 )  [virtual]

Filter a response signal of the neural microcircuit. Parameters: R  Response of the neural microcircuit. X  Target vector where to save the results. indices  Indices where to store the results in X. Returns: -1 if an error occured, 1 for success. Implements FilterFunction.

void AnalogFilter::reset (    )  [virtual]

Resets the information stored within the filter. Implements FilterFunction.

int AnalogFilter::setNumInputs (  unsigned int    nInputs )  [virtual]

Sets the number of input channels. Parameters: nInputs  The number of inputs. Returns: -1 if an error occured, 1 for success.

int AnalogFilter::updateInternal (    )  [virtual]

This function is called after parameters are updated. Reimplemented from FilterFunction. Reimplemented in UserAnalogFilter.
