Logarithms of complex numbers
WitrynaComplex logarithm. In complex analysis, a complex logarithm function is an "inverse" of the complex exponential function, just as the real natural logarithm ln x is the inverse of the real exponential … WitrynaY = log (X) returns the natural logarithm ln (x) of each element in array X. The log function’s domain includes negative and complex numbers, which can lead to unexpected results if used unintentionally. For negative and complex numbers z = u + i*w, the complex logarithm log (z) returns. log (abs (z)) + 1i*angle (z) If you want …

WitrynaBecause equation 3.21 yields logarithms of every nonzero complex number, we have defined the complex logarithm function. It is defined for all z 6= 0, and because … WitrynaEvaluating the natural log of complex numbers allows for logs with complex bases. Start with ln (x) = y, then apply change of base formula by converting to exponential form {e y = x}, taking a complex log of both sides {log_z (e y) = log_z (x)}, using log properties to bring y out front {y*log_z (e) = log_z (x)}, then replace y with it's ...
