OAFunc-expression

expression (OAFunc)

Works with all licenses.

A function of one argument, given via a UserFunc

expression Parameters

argMin (float, optional, default = minimum float)

the lower bound of the function’s domain

argMax (float, optional, default = maximum float)

the upper bound of the function’s domain

fmin (float, optional, default = minimum float)

the minimum function value (if specified, the value will be clamped above fmin)

fmax (float, optional, default = maximum float)

fmax: the maximum function value (if specified, the value will be clamped below fmax)

expression (string)

The function expression (can be given directly for simple functions), required if a UserFunc code block is not given; in this case, a UserFunc of kind=expression is automatically created with this expression.

outerBoundsValue (string, optional)

specifies the function value when the argument is outside the function’s domain.

• “null”: set value to zero

• “constant”: set value to the function’s value at the nearest domain boundary (i.e., argMin or argMax)

• “except”: halt the simulation with an error.

UserFunc (code block)

A UserFunc can be specified directly; it must take one argument, and return a scalar. This code block is required if a string expression is not given.

variable (string, optional, default = x)

Name of the variable in the expression.

Example expression Block

<OAFunc oafunc1>
  kind = expression
  expression = cos(x)
</OAFunc>
