URL: <http://savannah.gnu.org/bugs/?53351> Summary: A = expint(x>32+yi) doesn't result any imaginary number Project: GNU Octave Submitted by: mourice Submitted on: Thu 15 Mar 2018 12:47:18 PM UTC Category: Octave Function Severity: 3 - Normal Priority: 5 - Normal Item Group: Inaccurate Result Status: None Assigned to: None Originator Name: Originator Email: Open/Closed: Open Discussion Lock: Any Release: 4.2.1 Operating System: Any _______________________________________________________ Details: In Exponential integral : For complex values , the argument of the complex must be less than pi This condition is satisfied in the condition of real number(x) > 33 and imaginary (y) = any number in a suitable range Using MATLAB : >> A = expint(32.5+1i) A = 1.1811e-16 - 1.9663e-16i >> B = expint(44+1i) B = 9.0188e-22 - 1.4758e-21i Using Octave GNU Release 4.2.1 : >> A = expint(32.5+1i) ܀A = 1.1811e-016 >> B = expint(44+1i) y㌒ऀB = 9.0188e-022 _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?53351> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
