EigenTS

A minimalist typescript interface for the Eigen Tux matrix library (calculations run in WASM). Perform fast matrix-matrix multiplies, norm calculations, and system solves (Ax=b) in a mobile or desktop browser.

Currently, this demo focuses on dense matrix operations, but could easily be extended to include sparse matrix methods as well.

Running Eigen in WASM

This package uses emscripten to compile Eigen into a WASM module that can be run in a mobile or desktop browser.

Compile the Eigen bindings like this:

emcc src/eigen/eigen.cpp -o wasm/eigen.html -I ./Eigen -sEXPORTED_FUNCTIONS=_float_norm,_float_random_matrix,_float_matrix_matrix_mult,_float_system_solve,_float_matrix_matrix_add,_free -sEXPORTED_RUNTIME_METHODS=cwrap

This will produce a .wasm module and a wrapper .js file (as well as a demo .html page) in the /wasm directory.

Docker Environment

If you don't have or do not want to set up emscripten locally, you can use the supplied Dockerfile which installs all dependencies needed to create the WASM artifacts:

docker build -t emcc .
docker run -it --rm --entrypoint bash -v /path/to/EigenTS:/root/EigenTS emcc
cd /root/EigenTS
# run emscripten from the mounted repository to build eigen.cpp
