Interpolate plant properties using the 'Coupmodel' method.

Description

Creates a daily sequence for one year from parameters

Usage

plant_coupmodel(
  minval,
  maxval,
  doy.incr,
  doy.max,
  doy.min,
  shape.incr,

  maxdoy
)

Arguments

minval	Minimum value.
maxval	Maximum value.
doy.incr	Day of year when increasing from minval to maxval begins.
doy.max	Day of year when maxval is reached.
doy.min	Day of year when minval is reached again.
shape.incr	Shape parameter of the increasing phase.
shape.decr	Shape parameter of the decreasing phase.
maxdoy	Length of the year, 366 for leap years, 365 for normal years.
