Hi @kulikovv,
We didn’t compile LAPACK into our binary. However, since LAPCK is supported by the Accelerate.framework on iOS. You can manually enable it by following the steps below

Add a compiler flag - CMAKE_ARGS+=("-DUSE_LAPACK=ON") in build_ios.sh to tell cmake to compile LAPACK.
Follow the tutorial to run the build script and setup your project
Link Accelerate.framework to your project

Let me know if it works for you. Thanks.
