{"id":240569,"name":"th-cas","ecosystem":"hackage","description":"th-cas is a Computer Algebra System (CAS) for Haskell that performs symbolic\nmathematics operations at compile-time using Template Haskell. It provides both\ninteractive usage (similar to Mathematica) and compile-time optimization for\nmathematical computations with zero runtime overhead.\n.\nFeatures include:\n.\n* Symbolic differentiation with automatic simplification\n.\n* Symbolic integration using the Risch-Norman heuristic algorithm\n.\n* Linear and polynomial equation solvers\n.\n* Gröbner basis computation for multivariate polynomial systems\n.\n* Pattern matching and coefficient extraction\n.\n* Compile-time code generation via Template Haskell\n.\nThe library supports polynomial operations (GCD, LCM, factorization),\ntrigonometric and exponential functions, and advanced algorithms including\nHermite reduction for rational functions and the Extended Euclidean algorithm.\n.\nWith 150+ test cases, th-cas provides reliable symbolic computation for\nboth runtime and compile-time mathematical operations in Haskell.","homepage":"https://github.com/junjihashimoto/th-cas","licenses":"MIT","normalized_licenses":["MIT"],"repository_url":"https://github.com/junjihashimoto/th-cas","keywords_array":["library","math","mit","numeric","Propose
