time_interpolator_scalar()

subroutine time_interpolator::time_interpolator_scalar ( class(time_interpolator_t), intent(inout)  this, real(kind=rp), intent(in)  t, real(kind=rp), dimension(n), intent(inout)  f_interpolated, real(kind=rp), dimension(n, 0:this%order - 1), intent(in)  f_n, real(kind=rp), dimension(0:this%order), intent(in)  tlag, integer, intent(in)  n  )

Parameters

t	time to get interpolated field
f_interpolated	the interpolated field
f_n	an array of known fields
tlag	an array of the time steps corresponding to f_n.
n	size of the array
