  • Support for latest MS and Embarcadero compiler versions: RAD Studio 11 Alexandria, Visual Studio 2022
  • Support for Linux with GCC or CLang
  • Enhanced thread-safety for all linfit and nonlinfit functions.
  • Enhanced thread-safety for all linear system operations (LUD and SVD based).
  • P9 libraries utilizing AVX, AVX2, and FMA for highest performance on processors from 4th-generation Intel Core i (Haswell+) or AMD Excavator+ on.
  • CUDA-enabled libraries for all target compilers (currently only Windows).

New in CMATH for Lazarus 8.1.0 (Sep 2, 2021)

  • Lazarus version now Lazarus 2.0.12 / FPC 3.2.0
  • New functions:
  • V?_rsqrt, V?_rsquare, V?_rcubic, V?_rquartic
  • Syntax change:
  • All V?_trigrpi functions like VF_sinrpi, VD_cosrpi2, VE_tanrpi3
  • (functions of rational multiples r of Pi with r = P[i]/q)
  • are now declared with "unsigned q;" instead of "int q;".
  • This change made optimizations possible through which especially
  • the ...rpi2 functions have become much faster.
  • P9 libraries:
  • Now every function using the upper half of YMM registers calls
  • vzeroupper on exit. Thereby, the "dirty-state" penalty is avoided
  • which otherwise would strongly slow down any following SSE code.
  • MT libraries:
  • Can now work with up to 128 threads.
  • Significant speed improvements (64-bit only):
  • VF_scalprod
  • V?_sqrt, V?x_sqrt
  • V?_inv, V?x_inv
  • V?_square, V?x_square
  • V?_cubic, V?x_cubic
  • V?quartic, V?x_quartic
  • Bug fixes (64-bit):
  • VCD_pow (error for very small x.Im)
  • VCD_conj (would fail, if vector has only one single element)
  • VP?_absmaxind (last 1 to 3 elements might not be taken into account)
  • VUB_cmp_exclrange0Cind (last 1 to 3 elements possibly wrong)
  • VSI_minind (wrong results)

New in CMATH for Lazarus 7.3.3 (Jul 2, 2019)

  • Bug fix in cf_neg

New in CMATH for Lazarus 7.3 (Aug 24, 2018)
