This information is part of the Modelica Standard Library maintained by the Modelica Association.

This blocks computes the output y as the natural (base e) logarithm of the input u. Optionally, the input u can be processed conjugate complex, when parameter useConjugateInput is true. Depending on useConjugateInput the internal signal uInternal represents either the original or the conjugate complex input signal.

y = log(uInternal);

An error occurs if the elements of the input u is zero.

useConjugateInput	Value: false Type: Boolean Description: If true, input is processed conjugate complex
