Function Documentation

MovingAverage() [1/2]

template<typename Derived>

const Derived::PlainObject sablib::MovingAverage	(	const Eigen::MatrixBase< Derived > &	y,
		const unsigned int	n )

Calculates the simple moving average of the input signal.

Parameters

y	The data to be averaged.
n	Half-width of the moving average window (calculated using 2 * n + 1 points).

Returns

The data after applying the moving average.

Exceptions

std::invalid_argument

If n is zero.

Parameters

y	The data to be averaged.
n	Half-width of the moving average window (calculated using 2 * n + 1 points).

Returns

The data after applying the moving average.

WeightedMovingAverage() [1/2]

template<typename Derived>

const Derived::PlainObject sablib::WeightedMovingAverage	(	const Eigen::MatrixBase< Derived > &	y,
		const Eigen::MatrixBase< Derived > &	w )
