amici.ode_model.Expression

class amici.ode_model.Expression(identifier, name, value)[source]

An Expression is a recurring elements in symbolic formulas. Specifying this may yield more compact expression which may lead to substantially shorter model compilation times, but may also reduce model simulation time. Abbreviated by w.

__init__(identifier, name, value)[source]

Create a new Expression instance.

Parameters

identifier (sympy.core.symbol.Symbol) – unique identifier of the Expression
name (str) – individual name of the Expression (does not need to be unique)
value (sympy.core.expr.Expr) – formula

Methods Summary

`__init__`(identifier, name, value)	Create a new Expression instance.
`get_id`()	ModelQuantity identifier
`get_name`()	ModelQuantity name
`get_val`()	ModelQuantity value
`set_val`(val)	Set ModelQuantity value
