This is a short post that explains how to write a high-performance matrix multiplication program on modern processors. In this tutorial I will use a single core of the Skylake-client CPU with AVX2, but the principles in this post also apply to other processors with different instruction sets (such as AVX512).
Matrix multiplication is a mathematical operation that defines the product of

| # 1. Replace <AndroidKeyName> with the filename of the keyfile generated (see url) | |
| # 2. Replace <ProjectName> with the project name in the generated file form cordova, see path/to/my/project/platforms/android/bin and look for an APK if you need help | |
| # 3. Replace <AndroidKeyNameAlias> from the alias used when generating the key (see url again!) | |
| # 4. Edit path/to/my/project/platforms/android/AndroidManifest.xml and change "debuggable=false" (search for it!) | |
| # 5. Check path/to/my/project/Release/android for your sparkling new apk! | |
