Connections

Parameters

Modelica Standard Library

Description

The Logarithm (or Log) component computes the element-wise natural logarithm (base ⅇ) of the input u.

If base is specified to be something other than ⅇ, then it computes logbaseu.

Each input must be greater than 0.

The Signal Size parameter assigns the dimension of the input and output connectors.
