expDecay: Exponential decay function

In PathwaySpace: Spatial Projection of Network Signals along Geodesic Paths

Exponential decay function

Description

The expDecay function is used by PathwaySpace's methods for signal convolution and projection.

Usage

expDecay(x, signal = 1, decay = 0.001)

Arguments

x	A numeric vector of distances (in [0,1]).
signal	A single numeric value representing a signal.
decay	A decay factor (in [0,1]). This term indicates how much the signal decreases as a function of distance in pathway space. For example, at a specific distance defined by the pdist parameter (see circularProjection), the signal intensity will be the initial signal multiplied by decay. the weibullDecay function.

Value

A numeric vector; if missing 'x', it will return decay function.
