Detailed Description

Fundamental data structures

Three classes for storage and easy access to multi-indexes and floating point values. The majority of internal data-structures associated with the five types of grids can be represented as two-dimensional data (or array/list of tuples), the three classes here correspond to sorted or unsorted, integer or floating point data.

Function Documentation

spltVector2D()

template<typename T >

std::vector<T> TasGrid::spltVector2D	(	std::vector< T > const &	x,
		size_t	stride,
		int	ibegin,
		int	iend
	)

Take a vector logically organized into stips and strides and extract a sub-strip from every strip.

Used in copy subset of the values and the Data2D surplusses. The vector is organized in strips with the given stride and the returned vector has the same number of strips but containing the data between the ibegin and iend (not including iend).
