last function


Recalls value of X, another element, from previous time step. X must influence this element in order to be used in the equation. See prev, for a function that returns a previous value from this element itself.

This function has been replaced with the const_delay( ) and var_delay( ) functions, which are more general in allowing the value of a variable to be returned from an arbitrary number of time steps before.
