blockLog
Output the natural (base e) logarithm of the input (input <> '0' required)
Extends from Interfaces.ComplexSISO (Single Input Single Output continuous control block).
Information
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.
