function VFcu_localmaxima( h_Ind:uiVector; h_X:fVector; size:UIntSize ): UIntSize;
DescriptionThe indices of local maxima in X are stored in Ind and the number of local maxima is returned (this is the number of elements of Ind). A local maximum is defined as one element of X that is greater than both its neighbours to the right and to the left. That means that the zero'th and the last element of X (which have only one neighbour) cannot be local maxima. Also, if two adjacent elements are equal, none of them can be a local maximum.
