There is also a work in progress cmake build. The libraries can be built by opening the arm_cortexM_math.uvprojx project in MDK-ARM, selecting a specific target, and defining the optional preprocessor macros detailed above. The library installer contains a project file to rebuild libraries on MDK toolchain in the CMSIS\DSP\Projects\ARM folder. The library has been developed and tested with MDK version 5.14.0.0 The library is being tested in GCC and IAR toolchains and updates on this activity will be made available shortly.

The library ships with a number of examples which demonstrate how to use the library functions. Same header file will be used for floating point unit(FPU) variants. The Library supports single public header file arm_math.h for Cortex-M cores with little endian and big endian. Simply include this file and link the appropriate library in the application and begin calling the library functions. The library functions are declared in the public file arm_math.h which is placed in the Include folder. arm_ARMv8MMLldfsp_math.lib (Armv8-M Mainline, Little endian, DSP instructions, Single Precision Floating Point Unit).arm_ARMv8MMLld_math.lib (Armv8-M Mainline, Little endian, DSP instructions).arm_ARMv8MMLlfsp_math.lib (Armv8-M Mainline, Little endian, Single Precision Floating Point Unit).

If you want to use those functions, you'll have to modify the projects, include the missing files and rebuild. So, SVM, Bayes, Distance functions and experimental functions are not included in those libraries. Pre-built libraries will not be updated to contain new functions. The library installer contains prebuilt versions of the libraries in the Lib folder. The library has generally separate functions for operating on 8-bit integers, 16-bit integers, 32-bit integer and 32-bit floating-point values. The library is divided into a number of functions each covering a specific category:
