unsigned int	countEntriesAbove (DATATYPE *Array, int sz, double includeAbove)
	Utility to count how many entries above a specified value exist in a float array. More...

DATATYPE	getG (DATATYPE wuvar, SparseProjection sparseStruct, int x, int y)
	DEPRECATED Utility to get a synapse weight from a SPARSE structure by x,y coordinates NB: as the SparseProjection struct doesnt hold the preN size (it should!) it is not possible to check the parameter validity. This fn may therefore crash unless user knows max poss X. More...
