Sat, 12 Sep 2015 14:16:39 +0000 schloegl use macro ISNAN() instead of C++'s isnan() - because it supports all floating point formats not just double octave-forge
Sat, 12 Sep 2015 07:15:01 +0000 schloegl resulting values should be really converted to output data type octave-forge
Thu, 18 Jun 2015 15:09:49 +0000 schloegl check for sparse matrices and and convert to full if needed octave-forge
Wed, 20 Apr 2011 09:16:06 +0000 schloegl update contact e-mail and www address octave-forge
Tue, 15 Mar 2011 20:31:04 +0000 schloegl OpenMP support included octave-forge
Thu, 27 Jan 2011 17:10:36 +0000 schloegl fix web address octave-forge
Thu, 27 Jan 2011 16:39:17 +0000 schloegl replace <inttypes.h> with <stdint.h> octave-forge
Thu, 14 Jan 2010 17:50:16 +0000 schloegl partial support of lcc-win compiler octave-forge
Sun, 10 Jan 2010 22:05:59 +0000 schloegl use *.cpp instead of *.c octave-forge
Tue, 13 Oct 2009 22:43:28 +0000 schloegl fix version check for defining mwSize; set default ACC_LEVEL 0 octave-forge
Thu, 01 Oct 2009 12:13:51 +0000 schloegl default accuracy level set to 0; level 2 and 3 exchanged; added test to determine optimal accuracy level octave-forge
Wed, 30 Sep 2009 22:18:27 +0000 schloegl any combination of naive and Kahan summation with double and extended can be controlled through flag_accuracy_level octave-forge
Tue, 29 Sep 2009 15:29:06 +0000 schloegl increase accuracy by using Kahan's summation formula - this reduces the error by a factor of N; first tests show it slows down by about 25% octave-forge
Thu, 30 Jul 2009 07:30:14 +0000 schloegl COVM_MEX: prevent seg-fault for the case of X and Y have same starting location, but different size; COVM: remove redundant code, fix computation of mean of complex data octave-forge
Tue, 30 Jun 2009 12:15:57 +0000 schloegl using internally long double for increased accuracy octave-forge
Wed, 03 Jun 2009 20:28:12 +0000 schloegl some cleanup, and minor improvement octave-forge
Wed, 27 May 2009 21:51:02 +0000 schloegl support ml72 and earlier octave-forge
Thu, 07 May 2009 19:35:33 +0000 schloegl faster if X==Y, exploiting the fact that the output is symetric; docu improved octave-forge
Thu, 07 May 2009 09:33:46 +0000 schloegl NaN-tb: performance test of alternative algorithm, and optimization for speed; support complex matrices; bug fix in sumskipnan_mex octave-forge
Wed, 06 May 2009 16:21:10 +0000 schloegl NaN-tb: mex-version of covm added octave-forge
