`isStationary` (Model)

True if the model or a linear combination of its variables is stationary

Syntax

 flag = isStationary(m)
 flag = isStationary(m, name)
 flag = isStationary(m, expression)

Input arguments

m [ model ]

Model object.

name [ string ]

Transition variable name.

expression [ string ]

Text string defining a linear combination of transition variables; log variables need to be enclosed in log(...).

Output arguments

flag [ true | false ]

True if the model (if called without a second input argument) or the specified transition variable or combination of transition variables (if called with a second input argument) is stationary.

Description

Examples

In the following examples, m is a solved model object with two of its transition variables named x and y, with the latter being declared as a log variable:

    isStationary(m)
    isStationary(m, 'x')
    isStationary(m, 'log(y)')
    isStationary(m, 'x - 0.5*log(y)')
