Member Function Documentation

virtual double dmp::FunctionApprox::evalAt

(

double

x

)

[pure virtual]

Evaluate the function approximator at point x.

Parameters:

x	The point at which to evaluate

Returns:

The scalar value of the function at x

Implemented in dmp::FourierApprox, dmp::LinearApprox, and dmp::RadialApprox.

int dmp::FunctionApprox::getNumBases

(

)

[inline]

Returns the number of basis functions.

Returns:

The number of basis functions used by the approximator

Definition at line 70 of file function_approx.h.

std::vector<double> dmp::FunctionApprox::getWeights

(

)

[inline]

Returns the current weight vector.

Returns:

The current weight vector

Definition at line 75 of file function_approx.h.

virtual void dmp::FunctionApprox::leastSquaresWeights	(	double *	X,
		double *	Y,
		int	n_pts
	)		[pure virtual]

Computes the least squares weights given a set of data points.

Parameters:

X	A vector of the domain values of the points
Y	A vector of the target values of the points

Implemented in dmp::FourierApprox, dmp::LinearApprox, and dmp::RadialApprox.
