This is super strange since it provides access to hardware floats and such basic functions have been implemented with correct handling of branch cuts for decades (e.g.
length(A)-length(B) determines the difference of the lengths of the two arrays. z,B concatenates the arrays z and B horizontally. This is super strange since it provides access to hardware floats and such basic functions have been implemented with correct handling of branch cuts for decades (e.g. John Lutz: zeros(1,n) creates a row vector of n zeros. Sign of the real part of argument defines the sign of in result. Unfortunately MATLAB ignores signed zeros in all inverse trigonometric functions, sqrt, log and power (and apparently in special functions). ‡Logarithmic form of gives expression for function values along branch cut:
Unfortunately MATLAB ignores signed zeros in _all_ inverse trigonometric functions, sqrt, log and power (and apparently in special functions).
