Logarithm

Compute the natural logarithm or compute the logarithm using a specified base

Modelica Standard Library

	Description
	The Logarithm (or Log) component computes the element-wise natural logarithm (base $&ExponentialE;$ ) of the input $u$ . If base is specified to be something other than $&ExponentialE;$ , then it computes $\log_{base} (u)$ . Each input must be greater than 0. The Signal Size parameter assigns the dimension of the input and output connectors.

	Equations
	$y_{j} = \log (u_{j})$
