10.0.0 (2017-10-20)

• Switched to jbuilder and topkg

• API changes

  • trmm and trsm now do not label argument a anymore
  • Many matrix functions now support an optional patt argument, which can be used to specify rectangular, triagonal, trapezoidal, and pentagonal patterns on which to perform an operation.

  • New functions

    • Mat.sum_prod computes the sum of element-wise products of two matrices. Some use cases are already covered by Mat.gemm_trace, but the latter does not support patterns.
• Improved C-code to better support SIMD compiler optimizations
• Many internal improvements, including untagged and unboxed passing of parameters to and from external functions.
• Compilation now uses -march=native -O3 -ffast-math by default, which should be safe and exploit SIMD on platforms that support it to greatly improve performance of some operations.
• Improved documentation
• Improved configuration and build process
