diffusePDE

Function for diffusion of the Substance matrix

Description

The generic function diffusePDE implements the diffusion by the solving diffusion equation.

Usage

diffusePDE(object, init_mat, gridgeometry, lrw = NULL, tstep)

## S4 method for signature 'Substance'
diffusePDE(object, init_mat, gridgeometry, lrw = NULL, tstep)

Arguments

`object`	An object of class Substance.
`init_mat`	A matrix with values to be used by the diffusion.
`gridgeometry`	A list specifying the geometry of the Arena
`lrw`	A numeric value needed by solver to estimate array size (by default lwr is estimated in simEnv() by the function estimate_lrw())
`tstep`	A numeric value giving the time step of integration

Details

Partial differential equation is solved to model 2d diffusion process in the arena.
