Functions
template<typename IterT >
math::Histogram	histogram (const IterT &iter, double minVal, double maxVal, size_t numBins=10, bool threaded=true)
	Iterate over a scalar grid and compute a histogram of the values of the voxels that are visited, or iterate over a vector-valued grid and compute a histogram of the magnitudes of the vectors. More...
template<typename IterT >
math::Extrema	extrema (const IterT &iter, bool threaded=true)
	Iterate over a scalar grid and compute extrema (min/max) of the values of the voxels that are visited, or iterate over a vector-valued grid and compute extrema of the magnitudes of the vectors. More...
template<typename IterT >
math::Stats	statistics (const IterT &iter, bool threaded=true)
	Iterate over a scalar grid and compute statistics (mean, variance, etc.) of the values of the voxels that are visited, or iterate over a vector-valued grid and compute statistics of the magnitudes of the vectors. More...
template<typename IterT , typename ValueOp >
math::Extrema	extrema (const IterT &iter, const ValueOp &op, bool threaded)
	Iterate over a grid and compute extrema (min/max) of the values produced by applying the given functor at each voxel that is visited. More...
template<typename IterT , typename ValueOp >
math::Stats	statistics (const IterT &iter, const ValueOp &op, bool threaded)
	Iterate over a grid and compute statistics (mean, variance, etc.) of the values produced by applying the given functor at each voxel that is visited. More...
template<typename OperatorT , typename IterT >
math::Stats	opStatistics (const IterT &iter, const OperatorT &op=OperatorT(), bool threaded=true)
	Iterate over a grid and compute statistics (mean, variance, etc.) of the values produced by applying a given operator (see math/Operators.h) at each voxel that is visited. More...
template<typename OperatorT , typename IterT >
math::Extrema	opExtrema (const IterT &iter, const OperatorT &op=OperatorT(), bool threaded=true)
	Same as opStatistics except it returns a math::Extrema vs a math::Stats. More...
