|GRN (Genetic Regulatory Network Arrows)||Reference Home|
GRN[v,β,n,h] is an uninstantiated function that encapsulates the parameters used in a Genetic Regulatory Network reaction. GRN arrow functions are based on neural-network (connectionist) models of genetic regulation.
GRN[v, β, n] is equivalent to GRN[v, β, n, 0].
GRN[v, β] is equivalent to GRN[v, β, 1, 0].
GRN[v] is equivalent to GRN[v, 1, 1, 0].
GRN is equivalent to GRN[1, 1, 1, 0].
The expressions GRN[...] and grn[...] are equivalent and may be used interchangeably.
