lfst alternatives and similar packages
Based on the "Math" category.
Alternatively, view lfst 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. 
computationalalgebra
GeneralPurpose Computer Algebra System as an EDSL in Haskell 
dimensional
Dimensional library variant built on Data Kinds, Closed Type Families, TypeNats (GHC 7.8+). 
mwcrandom
A very fast Haskell library for generating high quality pseudorandom numbers. 
numhask
A haskell numeric prelude, providing a clean structure for numbers and operations that combine them.

Haskel binding for Eigen library. Eigen is a C++ template library for linear algebra: matrices, vectors, numerical solvers, and related algorithms.
Clean code begins in your IDE with SonarLint
* Code Quality Rankings and insights are calculated and provided by Lumnify.
They vary from L1 to L5 with "L5" being the highest.

lfst  LFuzzy Set Theory implementation in Haskell
Description
If X is a collection of objects denoted generically by x, then a fuzzy set F(A) in X is a set of ordered pairs. Each of them consists of an element x and a membership function which maps x to the membership space M. The current implementation is inspired by the work of J.A. Goguen LFuzzy Sets [1].
Setup
This library could be easily compiled using cabal issuing the command cabal build
in the root directory.
Usage
Using this library you can easily apply the Extension Principle [2] in the following way:
let fuzzy_set = fromList [(1, Godel 0.5), (0, Godel 0.8), (1, Godel 1.0), (2, Godel 0.4)]
fmap (^2) fuzzy_set
> FuzzySet {(0, Godel 0.8), (1, Godel 1.0), (4, Godel 0.4)}
