Fast C++17 Header-Only Expression Template Matrix and Tensor Library

Tense

Tense is a C++17 matrix and tensor library. It is a fast expression template library that uses auto-vectorization. It also uses CBLAS and LAPACKE for linear algebra operations.

Installation

You can install Tense system-wide by downloading the latest release. Make sure you have CMake, a C++ compiler (the newer version, the faster), CBLAS and LAPACKE available on your system. Then run these in repository directory:

mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release -DTENSE_NATIVE=ON -DTENSE_INSTALL=ON -DTENSE_TESTS=OFF -DTENSE_EXAMPLES=OFF -DCMAKE_INSTALL_PREFIX=/usr/local/ ..
sudo cmake --install .

The CMake options are:

• TENSE_INSTALL: Create install for Tense.
• TENSE_TESTS: Build the tests for Tense.
• TENSE_EXAMPLES: Build the examples for Tense.
• TENSE_NATIVE: Targets that link against Tense are specifically tuned for host CPU. This makes auto-vectorization possible.

Note that this installs BLASW library too. Then you can use it in CMake:

find_package(Tense REQUIRED)
add_executable(myexec main.cpp)
target_link_libraries(myexec Tense::Tense)

Or you can use Tense as a CMake subdirectory by cloning the repository and putting it in your source directory and use it in CMake:

add_subdirectory(Tense/)
add_executable(myexec main.cpp)
target_link_libraries(myexec Tense::Tense)
