Installation

Requirements

• MATLAB R2020b+ or GNU Octave 7+
• C compiler (optional) for MEX acceleration:
  • macOS: Xcode Command Line Tools
  • Linux: GCC
  • Windows: MSVC
• No toolbox dependencies

Setup

1. Clone or download the repository
2. In MATLAB/Octave, navigate to the FastPlot directory
3. Run install:

install;

This adds the library paths:

• libs/FastPlot — core plotting engine
• libs/SensorThreshold — sensor and threshold system
• libs/EventDetection — event detection and viewer
• libs/Dashboard — dashboard engine and widgets
• libs/WebBridge — TCP server for web-based visualization

MEX Compilation (Optional)

For maximum performance, compile the C MEX accelerators:

cd libs/FastPlot
build_mex();

This auto-detects your architecture and compiles:

• binary_search_mex — O(log n) visible range lookup (10-20x faster)
• minmax_core_mex — per-pixel MinMax with SIMD (3-10x faster)
• lttb_core_mex — LTTB downsampling with SIMD (10-50x faster)
• violation_cull_mex — fused violation detection + pixel culling

SIMD support:

• Apple Silicon (arm64): NEON intrinsics
• x86_64: AVX2 with SSE2 fallback

If MEX files are not compiled, pure-MATLAB fallbacks are used automatically with identical behavior.

Verify Installation

install;
addpath('tests');
run_all_tests();

Or run a quick example:

install;
