* uhd: math: Replace wrap-frequency math with a single functionMartin Braun2021-10-191-0/+8
| | | | | | | | | In multiple places in the UHD code, we were doing the same calculation for a wrapped frequency (wrap it into the first Nyquist zone). This math was using boost::math, too. Instead of editing every instance, we create a new function, uhd::math::wrap_frequency(), and replace all of its separate implementations with this function. The new function also no longer relies on boost::math::sign.
* uhd: math: Add a sign() functionMartin Braun2021-10-191-0/+7
| | | | | We've been having issues with moving locations of Boost headers for this function, and it's simple enough to implement ourselves.
* uhd: math: Add interpolation.hppMartin Braun2020-04-071-10/+0
| | | | | | | | - Moves linear_interp from cal to utils - Moves the interp_mode enum class to interpolation.hpp - Adds three interpolation methods for maps: at_interpolate_1d(), at_nearest(), at_lin_interp() - Adds unit tests
* uhd: math: Add linear_interp()Martin Braun2020-03-181-1/+10
| | | | This lets you linearly interpolate between two points.
* math: Replace boost::*::{lcm,gcd}() with portable versionsMartin Braun2019-01-181-3/+7
| | | | | | Boost changed the lcm() and gcd() functions in Boost 1.67. This creates portable UHD versions to be used instead. They use various Boost versions under the hood conditionally.
* math: Remove uhd::math::log2, replace with std::log2Martin Braun2019-01-181-6/+3
| | | | | Now that we're C++11, we can assume the existence of said symbol and need no more portability hacks.
* uhd: mpm: apply clang-format to all filesBrent Stapleton2019-01-161-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Applying formatting changes to all .cpp and .hpp files in the following directories: ``` find host/examples/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find host/tests/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find host/lib/usrp/dboard/neon/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find host/lib/usrp/dboard/magnesium/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find host/lib/usrp/device3/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find host/lib/usrp/mpmd/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find host/lib/usrp/x300/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find host/utils/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find mpm/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file ``` Also formatted host/include/, except Cpp03 was used as a the language standard instead of Cpp11. ``` sed -i 's/ Cpp11/ Cpp03/g' .clang-format find host/include/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file ``` Formatting style was designated by the .clang-format file.
* uhd: Update license headersMartin Braun2018-02-191-1/+2
| | | | | | | All copyright is now attributed to "Ettus Research, a National Instruments company". SPDX headers were also updated to latest version 3.0.
* Move all license headers to SPDX format.Martin Braun2017-12-221-12/+1

* Remove all boost:: namespace prefix for uint32_t, int32_t etc. (fixed-width ↵Martin Braun2016-11-081-1/+1
| | | | | | | | types) - Also removes all references to boost/cstdint.hpp and replaces it with stdint.h (The 'correct' replacement would be <cstdint>, but not all of our compilers support that).
* math: Added a portable log2()Martin Braun2014-11-201-0/+29
