After almost 3 years we are proud to announce that IT++ 4.3.0 is the next release of the current IT++ master branch. It uses an compilation system based on cmake and adds a number of new features and bug fixes as described in the release notes.
As usual, if you encounter any problems with this release, please ask for help on the IT++ Help forum.

IT++ 4.0.6 is the next maintenance release of the current IT++ stable branch (itpp-4-0). It fixes all the reported and noticed bugs since IT++ 4.0.5 was released and adds a few other minor modifications as described in the release notes.

IT++ is a C++ library of mathematical, signal processing and communication system routines/functions. Its main use is in simulation of communication systems or for performing research in the area of communications.

Although IT++ 4.0.2 was published only a few days ago, we decided to prepare the next maintenance release quite fast. The reason for this immediate action is that IT++ 4.0.1 and 4.0.2 use a wrong method to call the BLAS zdotu_ function, which causes the blas_test and vec_test failures on some architectures (e.g. Debian sparc/alhpa/arm) or when using non-standard optimisation flags (e.g. -fomit-frame-pointer of the GCC). The problem is due to the fact that a std::complex<double> C++ type is not compatible with COMPLEX in Fortran. This appears to be especially visible when calling the Fortran functions that return a complex result. IT++ 4.0.3 release should fix this regression.... read more

IT++ 4.0.2 is the second maintenance release of the current IT++ stable branch (itpp-4-0).

It fixes the reported bugs: wrong result of the log_add() function [1863940] and problem with testing zdotu_ calling convention on 64-bit systems [1855481]. Two other minor bugs in GF2mat_sparse_alist::from_sparse() and Parser::get() functions are also fixed. Finally, a set of documentation improvements is included in this release. For a full list of changes please have a look at the release notes.... read more

IT++ 4.0.1 is the first bug-fix release of the current stable itpp-4-0 branch. As usual, the maintenance release is backward compatible with previous versions from the same branch, because only bug-fixes and modifications that do not break the interface have been included.

The detection of external BLAS/LAPACK libraries has been improved. It is now possible to use Intel MKL or Apple's Accelerate Framework without a Fortran compiler. SVD and QR decompositions are now calculated much faster. Also, itpp-config and pkg-config's itpp.pc scripts have been improved, so the use of an additional explicit "--static" switch should be not necessary in most common cases. Finally, all bugs reported for version 4.0.0 have been fixed. For a full list of changes in this release please have a look at the release notes.... read more

IT++ 4.0.0 is the new stable release based on itpp-3-99 development branch. It supersedes our previous 3.10.x stable versions. After over one and a half year of intensive development it includes a lot of new features and improvements with respect to IT++ 3.10.12 release (the previous stable version).

The source packages with IT++ 4.0.0 release can be downloaded using the following links:

IT++ 4.0.0-rc2 is the second release candidate of our next stable series based on itpp-3-99 development branch. It supersedes our previous 3.10.x stable series. After almost one and a half year of intensive development it includes a lot of new features and improvements with respect to IT++ 3.10.12 (the last stable release of 3.10.x series).

This release fixes some BLAS-related problems when linking IT++ with MKL. It also improves configuration of the path to include files required by FFT/IFFT. Finally it adds a check for allowed 0 or 1 values in ">>" operator of bin class. Without this fix, bvec or bmat could be initialised with other integer values.... read more

IT++ 4.0.0-rc1 is the first release candidate of our next stable series based on itpp-3-99 development branch. It supersedes our previous 3.10.x stable series. After almost one and a half year of intensive development it includes a lot of new features and improvements with respect to IT++ 3.10.12 (the last stable release of 3.10.x series).

A brief summary of the most important new features and modifications is included in the release notes:

This minor bug-fix release fixes a serious regression, which appeared in just released 3.99.3 development version. Here is a short description of the fixed problem:

"Wrong declaration of zdotu_() BLAS function interface caused segmentation faults when IT++ was compiled with "-fomit-frame-pointer" flag. To fix this problem a Fortran wrapper function zdotusub_() has been added to IT++. This wrapper function comes from NetLib's CBLAS package."... read more

Warning!
There is a bug in this release related to zdotu_ BLAS routine used in Vec::dot() method for complex vectors. It results in a segmentation fault when compiled with "-fomit-frame-pointer" optimisation flag. Bug-fix release 3.99.3.1 will be soon released.

IT++ 3.99.3 is the last development release of IT++ 3.99.x series. The upcoming 4.0.0 stable release will be based on this version after a certain stabilisation period. Therefore we encourage everyone to switch to this version and report any problems and bugs on the IT++ Help forum. The interface of this release should be compatible with the next 4.0.x stable releases.... read more

This bug-fix release is intended to be the final release of the current stable
branch (3.10.x). The development branch (3.99.x) will soon become a new stable
branch, starting from version 4.0.0. Therefore, we recommend to start using
3.99.x releases instead of 3.10.x ones as soon as possible.

As usual, this release includes only bug-fixes and minor modifications that
do not change the interface. The most important bugs fixed in this release
are related to: "+=" and "-=" operators of the Vec class; binom(), binom_i()
and hadamard() functions; broken MSVC++ project files; and MKL library detection macros.... read more
