Two-quadrant inverse tangent

Matlab/Scilab equivalent

Matlab Scilab

Particular cases

When the input x is imaginary and abs(x)>=1, the real part of the result differs from Scilab vs Matlab or Octave:

Scilab Octave Matlab
atan(-2i)-π/2 - B.i-π/2 - B.iπ/2 - B.i
atan(-i) Nan - Inf 0 - Inf 0 - Inf
atan(i) Nan + Inf 0 + Inf 0 + Inf
atan(2i) π/2 + B.i π/2 + B.i-π/2 + B.i
