Functions
double	dGetInterpolatedValue (vector< double > const pVdXdata, vector< double > const pVdYdata, double dX, bool bExtrapolate)

double	dGetInterpolatedValue (vector< int > const pVnXdata, vector< double > const pVdYdata, int nX, bool bExtrapolate)

int	nFindIndex (vector< double > const *pVdX, double const dValueIn)
	This is used by VdInterpolateCShoreProfileOutput, it returns the index of the value in pVdX which is less than or equal to the absolute difference between dValueIn and the pVdX value.

vector< double >	VdInterpolateCShoreProfileOutput (vector< double > const pVdX, vector< double > const pVdY, vector< double > const *pVdXNew)
	Returns a linearly interpolated vector of doubles, to make CShore profile output compatible with CME. The array pVdY has been output by CShore and so always has length CSHOREARRAYOUTSIZE, whereas all other arrays have sizes which depend on CME at runtime.

◆ dGetInterpolatedValue() [1/2]

double dGetInterpolatedValue	(	vector< double > const *	pVdXdata,
		vector< double > const *	pVdYdata,
		double	dX,
		bool	bExtrapolate )

From https://cplusplus.com/forum/general/216928/ Returns interpolated value at x from parallel arrays (VdXdata, VdYdata). Assumes that VdXdata has at least two elements, is sorted and is strictly monotonically increasing. The boolean argument extrapolate determines behaviour beyond ends of array (if needed). For this version, both lots of data are doubles

◆ dGetInterpolatedValue() [2/2]

double dGetInterpolatedValue	(	vector< int > const *	pVnXdata,
		vector< double > const *	pVdYdata,
		int	nX,
		bool	bExtrapolate )

From https://cplusplus.com/forum/general/216928/ Returns interpolated value at x from parallel arrays (VdXdata, VdYdata). Assumes that VdXdata has at least two elements, is sorted and is strictly monotonically increasing. The boolean argument extrapolate determines behaviour beyond ends of array (if needed). For this version, one lot of data is integer and the other is double

◆ nFindIndex()

int nFindIndex	(	vector< double > const *	pVdX,
		double const	dValueIn )

This is used by VdInterpolateCShoreProfileOutput, it returns the index of the value in pVdX which is less than or equal to the absolute difference between dValueIn and the pVdX value.

◆ VdInterpolateCShoreProfileOutput()

vector< double > VdInterpolateCShoreProfileOutput	(	vector< double > const *	pVdX,

		vector< double > const *	pVdXNew )

Returns a linearly interpolated vector of doubles, to make CShore profile output compatible with CME. The array pVdY has been output by CShore and so always has length CSHOREARRAYOUTSIZE, whereas all other arrays have sizes which depend on CME at runtime.
