mapX2YInt

function [i, t] = mapX2YInt(xi, order)

mapX2YInt Map the index of a systems form variable x to a variable and horizon of the dynamic system.

[i, t] = mapX2YInt(xi, order) returns the variable index i and the horizon t such that x_{xi} corresponds to y_{i, t}. This is the reverse of mapY2XInt.

Arguments

xi (integer): Index of the variable in the systems form.
order (vector): Ordering of variables given by the transmission matrix.

Returns

i (integer): Index of the variable in the original ordering.
t (integer): Horizon of the variable. The contemporaneous period is horizon 0.
