Martin Braun	5ee6b828de	uhd: math: Replace wrap-frequency math with a single function ... 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.	2021-10-19 12:21:33 -07:00
Martin Braun	91c10b66c2	uhd: math: Add a sign() function ... We've been having issues with moving locations of Boost headers for this function, and it's simple enough to implement ourselves.	2021-10-19 12:21:33 -07:00
Martin Braun	d9f4d540ef	uhd: math: Add interpolation.hpp ... - 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	2020-04-07 07:24:19 -05:00
Martin Braun	07b85b6dcc	uhd: math: Add linear_interp() ... This lets you linearly interpolate between two points.	2020-03-18 12:53:50 -05:00
Martin Braun	7fab6b807e	math: Replace boost::*::{lcm,gcd}() with portable versions ... 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.	2019-01-18 09:37:12 -08:00
Martin Braun	11c7e561fc	math: Remove uhd::math::log2, replace with std::log2 ... Now that we're C++11, we can assume the existence of said symbol and need no more portability hacks.	2019-01-18 09:37:12 -08:00
Brent Stapleton	967be2a4e8	uhd: mpm: apply clang-format to all files ... 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.	2019-01-16 11:40:23 -08:00
Martin Braun	ae5211d71d	uhd: Update license headers ... All copyright is now attributed to "Ettus Research, a National Instruments company". SPDX headers were also updated to latest version 3.0.	2018-02-19 16:54:52 -08:00
Martin Braun	4f948e2c8b	Move all license headers to SPDX format.	2017-12-22 10:45:51 -08:00
Martin Braun	99c2730bc9	Remove all boost:: namespace prefix for uint32_t, int32_t etc. (fixed-width 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).	2016-11-08 08:02:22 -08:00
Martin Braun	27aa985f45	math: Added a portable log2()	2014-11-20 23:28:37 +01:00
