- brian2.equations.codestrings.is_constant_over_dt(expression, variables, dt_value)[source]
Check whether an expression can be considered as constant over a time step. This is not the case when the expression either:
contains the variable
t
(except as the argument of a function that can be considered as constant over a time step, e.g. aTimedArray
with a dt equal to or greater than the dt used to evaluate this expression)refers to a stateful function such as
rand()
.
