Functions
Eigen::MatrixXd	obsidian::world::sqExp (const Eigen::MatrixXd &x1, const Eigen::MatrixXd &x2, const Eigen::VectorXd &lengthScale, bool noisy=false)
	Compute a covariance matrix using the square exponential function. More...
Eigen::MatrixXd	obsidian::world::sqExp2d (const Eigen::Matrix< double, 2,-1 > &x1, const Eigen::Matrix< double, 2,-1 > &x2, const Eigen::Vector2d &lengthScale, bool noisy=false)
	Compute a covariance matrix using the squared exponential function. This function is faster than sqExp, but only applies when the dimensions of the points is 2 (which is true for control points and query points). More...
Eigen::Vector2d	obsidian::world::autoLengthScale (const std::pair< double, double > &x1x2, const std::pair< double, double > &y1y2, uint resx, uint resy)
	Get an appropriate length scale given the grid resolution and a smoothing factor. More...
