Viatcheslav Nesterov committed [r140]
Bugs with Ziel - result dissociation corrected
-
minor
-
Writing docs.
-
Version 0.6.0
-
-
Reintegrating uDFT branch into trunk
-
-
uFFT rewritten for use of open arrays and functions instead of procedures
-
For InsertFrom, variant with OpenArray added
-
forprint of vectors, open array are used
-
uMatrix: open arrays instead of TVector used in operators
-
Convolution works for signal length = 1
-
Add an lmath project_group for easier first manual usage
-
Target created in lpg (attachment was empty) and included into the library.
-
uFindChebyshevCoeffs.pas added; some error codes added and used in lmDSP/lmdsp.lpk; in some places open array parameters used instead of TVector.
-
1. uFFT and uDFT moved from lmRegression to lmDSP
-
Working uDFT, corrected uFFT, uCompVecUtils, Euler constant, predefined variables Pi and Euler in uEval, new Demo program for Fourier transforms.

Hi! Many thanks for your work! Little problem is that I am user of Lazarus release version myself and cannot try your work before including in the package, though in principle I find it potentially very useful. I think, for now I leave this ticket open, and include your work in LMath library immediately after project groups are included into release of Lazarus. Many thanks once more!

wp created ticket #2
Add an lmath project_group for easier first manual usage

Hi! nv_icons.lrs together with original .png files are included in the distributed file lmath.zip. Being a sole developer I did not see much sense in including them into svn. But as I see now, many users prefer to check out svn rather than download distribution files, I added the icons to svn. At the next svn update you will have them. Best regards, and thanks for reports and interesting discussion at the forum.

Thanks! lmath.lpk and all it's packages compile fine now. However I have the following error while trying to compile lmcomponents.lpk: Hint: (11030) Start of reading config file C:\PRG\Lazarus\Fixes20x32x\fpc\bin\i386-win32\fpc.cfg Hint: (11031) End of reading config file C:\PRG\Lazarus\Fixes20x32x\fpc\bin\i386-win32\fpc.cfg Free Pascal Compiler version 3.2.1-r45984 [2020/08/02] for i386 Copyright (c) 1993-2020 by Florian Klaempfl and others (1002) Target OS: Win32 for i386 (3104) Compiling lmcomponents.pas...
-
lmath.lpk created which imports all LMath packages. Now it is possible for a program to import lmath.lpk instead of importing every single package.

Error in FindSigma corrected

Hi! Many thanks for your report. Indeed, seems that I forgot to commit these two files, now they are in the repo. Now they are committed. But generally, I recommend to download zip files from here rather then from the repository, unless you are interested in the latest development. I use Trunk for ongoing development, hence it may be untested and even not working. Best regards, Viatcheslav
