Some context: This library was, in addition to my C++ bindings to BLAS [1], written to be able to improve the performance of the linear algebra library Vectorious [2] and will eventually be included there.
These bindings are direct C++ bindings to LAPACK, in contrast to node-lapack [3] which uses the foreign function interface and therefore inherits its call overhead. The bindings also use the TypedArray equivalents to C/Fortran single- and double precision arrays (Float32Array and Float64Array respectively) instead of regular arrays for extra performance.
