an algorithm that computes new field samples from amplitudes and random field model



## Constructor &amp; Destructor Documentation

 [ApproximateRandomField](class_approximate_random_field.xhtml)  ( bool  *enforce\_equal\_idents* = `false`) 

constructor

Parameters enforce\_equal\_identsif true, then the same quantity idents are used as the input idents (is only used in optiSLang's simulation flow. Usually objects with that quantity ident already exist!)
