How can I use the BLAS and LAPACK libraries with Speedgoat and Simulink Real-Time (SLRT)?

[MathWorks Support Team]

The LAPACK and BLAS libraries are already compiled and shipped by MathWorks in the Simulink Real-Time Target Support Package since MATLAB R2022a (and BLAS since R2020b).

Once the SLRT Target Support Package is installed, you will find the necessary headers and libraries in the paths shown below:

BLAS: C:\ProgramData\MATLAB\SupportPackages\R2022b\toolbox\slrealtime\target\supportpackage\qnx710\target\qnx7\usr\include\openblas

LAPACK: C:\ProgramData\MATLAB\SupportPackages\R2022b\toolbox\slrealtime\target\supportpackage\qnx710\target\qnx7\x86_64\usr\local\lib

openBLAS reference: OpenMathLib/OpenBLAS: OpenBLAS is an optimized BLAS library based on GotoBLAS2 1.13 BSD version

You can use the headers and the libraries directly in your custom code/S-Function without worrying about the compilation and deployment process. Please consider this page in the doc as the main reference for integrating and using external libraries into SLRT applications:
