HLSL Linear Algebra Examples

This repository contains standalone HLSL matrix multiplication shaders and native D3D12 linear algebra samples.

Implementation Examples

This repository demonstrates different approaches based on feature availability:

• Standalone shaders: three GEMM implementations using groupshared memory, wave-scope matrix operations, and threadgroup-scope matrix operations.
• sin-network: a complete native D3D12 sample that approximates sin(x) with a 16-neuron network and thread-scope matrix-vector multiplication. Its README contains build instructions and a walkthrough of the C++ host, HLSL shader, resource layout, and dispatch flow.
• xor-network: a complete native D3D12 sample that classifies the four XOR inputs as one batch with a 2 -> 4 -> 1 network, compares FP16 threadgroup matrix multiplication with a wave-tiled GEMM implementation, and verifies both output matrices agree.
