URL: <http://savannah.gnu.org/bugs/?43349> Summary: asin behaves differently from Matlab for arguments larger than 1 Project: GNU Octave Submitted by: biloti Submitted on: Qui 02 Out 2014 11:31:48 BRT Category: Octave Function Severity: 3 - Normal Priority: 5 - Normal Item Group: Matlab Compatibility Status: None Assigned to: None Originator Name: Ricardo Biloti Originator Email: Open/Closed: Open Discussion Lock: Any Release: 3.8.1 Operating System: GNU/Linux _______________________________________________________ Details: Let x be a real value greater than 1 (x > 1). Then Matlab reports that asin (x) = pi/2 - a*i, for some a > 0 However Octave produces the complex conjugate asin (x) = pi/2 + a*i This occurs only for real x > 1. Both Matlab and Octave agree for real x <=1. _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?43349> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
