URL: <http://savannah.gnu.org/bugs/?38870> Summary: load reads stochastic data from MAT -file Project: GNU Octave Submitted by: None Submitted on: Thu 02 May 2013 05:11:57 PM UTC Category: None Severity: 3 - Normal Priority: 5 - Normal Item Group: Incorrect Result Status: None Assigned to: None Originator Name: Risto Vanhanen Originator Email: address@hidden Open/Closed: Open Discussion Lock: Any Release: 3.2.4 Operating System: GNU/Linux _______________________________________________________ Details: Load function gives out stochastic data for a few element MAT -file. Used file (results.mat) attached: all included doubles are 0xEEEEEEEE. Matlab 8.0.0.783 reads this correctly. Saving in Matlab and reloading in Octave solves the acute problem, but does not really solve the underlying problem in Octave. Here is the backlog: ---------------------------------------------- octave:1> version ans = 3.2.4 octave:2> clear; run2 = load('results.mat'); run2.q ans = 6.9225e-310 6.9225e-310 2.1220e-314 6.9225e-310 2.3715e-322 2.3715e-322 6.9567e-317 6.9566e-317 6.8847e-317 1.1932e+190 4.7430e-322 3.1620e-322 6.9333e-317 6.9322e-317 6.9953e-317 6.9737e-317 9.0236e-317 9.0261e-317 9.0261e-317 1.0326e-321 6.8898e-317 9.0182e-317 6.8861e-317 4.9407e-324 0.0000e+00 2.4209e-322 6.9553e-317 7.0220e-317 9.1979e-317 6.9225e-310 4.7430e-322 3.1620e-322 9.0182e-317 octave:3> clear; run2 = load('results.mat'); run2.q ans = 6.9225e-310 6.9225e-310 1.5810e-322 2.3715e-322 9.2235e-317 5.4347e-323 2.1220e-314 6.2590e-85 3.7683e-317 1.3488e-321 6.9225e-310 6.9995e-317 8.1152e-317 8.3198e-317 8.3198e-317 6.3734e-322 8.2575e-317 6.9919e-317 0.0000e+00 0.0000e+00 8.3072e-317 7.7742e-317 7.7742e-317 3.2114e-322 9.2222e-317 6.9543e-317 0.0000e+00 0.0000e+00 8.3547e-317 8.3429e-317 1.5810e-321 3.1620e-322 6.8920e-317 octave:4> whos -file 'results.mat' Variables in the file results.mat: Attr Name Size Bytes Class ==== ==== ==== ===== ===== q 33x1 264 double w 33x1 264 double xxxxxxx 1x12 12 char yyyyyy 34x1 272 double z 33x33 8712 double Total is 1201 elements using 9524 bytes ---------------------------------------------- _______________________________________________________ File Attachments: ------------------------------------------------------- Date: Thu 02 May 2013 05:11:57 PM UTC Name: results.mat Size: 10kB By: None Test data. <http://savannah.gnu.org/bugs/download.php?file_id=27995> _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?38870> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
