thcas alternatives and similar packages
Based on the "Math" category.
Alternatively, view thcas alternatives based on common mentions on social networks and blogs.

vector
An efficient implementation of Intindexed arrays (both mutable and immutable), with a powerful loop optimisation framework . 
statistics
A fast, high quality library for computing with statistics in Haskell. 
HerbiePlugin
GHC plugin that improves Haskell code's numerical stability 
hgeometry
HGeometry is a library for computing with geometric objects in Haskell. It defines basic geometric types and primitives, and it implements some geometric data structures and algorithms. The main two focusses are: (1) Strong type safety, and (2) implementations of geometric algorithms and data structures that have good asymptotic running time guarantees. 
dimensional
Dimensional library variant built on Data Kinds, Closed Type Families, TypeNats (GHC 7.8+). 
computationalalgebra
GeneralPurpose Computer Algebra System as an EDSL in Haskell 
numhask
A haskell numeric prelude, providing a clean structure for numbers and operations that combine them. 
mwcrandom
A very fast Haskell library for generating high quality pseudorandom numbers. 
poly
Fast polynomial arithmetic in Haskell (dense and sparse, univariate and multivariate, usual and Laurent) 
cf
"Exact" real arithmetic for Haskell using continued fractions (Not formally proven correct) 
optimization
Some numerical optimization methods implemented in Haskell 
equationalreasoning
Agdastyle equational reasoning in Haskell 
safedecimal
Safe and very efficient arithmetic operations on fixed decimal point numbers 
monoidsubclasses
Subclasses of Monoid with a solid theoretical foundation and practical purposes 
eigen
Haskel binding for Eigen library. Eigen is a C++ template library for linear algebra: matrices, vectors, numerical solvers, and related algorithms. 
modulararithmetic
A useful type for working with integers modulo some constant.
InfluxDB  Power RealTime Data Analytics at Scale
* Code Quality Rankings and insights are calculated and provided by Lumnify.
They vary from L1 to L5 with "L5" being the highest.

README
thcas : Compiletime CAS(Computer Algebra System)
CAS(Computer Algebra System) operations like diff are done at compiletime. Compile time operations is done in TemplateHaskell.
Interactive Usage
thcas
supports interactive usage like mathematica.
To start repl, type "stack ghci".
Variables are defined by V
of dataconstructor.
A example of intertative usage is below.
$ stack ghci
...
*Algebra.CAS>
*Algebra.CAS> let x = V "x"
*Algebra.CAS> let y = V "y"
*Algebra.CAS> x^2 + 2*x + x^2
2*x + 2*(x^2)
*Algebra.CAS> diff (x^2 + 2*x + x^2) x
2 + 4*x
*Algebra.CAS> linsolve [x+y=:2,xy=:3]
Just [(x,5/2),(y,1/2)]
*Algebra.CAS> subst [(x,1)] $ diff (x^2 + 2*x + x^2) x

Usage at compile time
Write diff function var
with Quotes of TemplateHaskell.
diff
makes a diffirential of the function at compiletime.
So there is no overhead at executiontime.
A example is below.
Write following code with quotes.
import Algebra.CAS.TH
myfunc :: Int > Int
myfunc x = $(diff [x*x+2*x+1] [x])
At compile time, the quotes is translated to 2*x+2
.
import Algebra.CAS.TH
myfunc :: Int > Int
myfunc x = 2*x+2
