gonum alternatives and similar packages
Based on the "Science and Data Analysis" category

gosl
Go scientific library for linear algebra, FFT, geometry, NURBS, numerical methods, probabilities, optimisation, differential equations, and more. 
gonum/mat64
The general purpose package for matrix computation. Package mat64 provides basic linear algebra operations for float64 matrices. 
TextRank
TextRank implementation in Golang with extendable features (summarization, weighting, phrase extraction) and multithreading (goroutine) support. 
sparse
Go Sparse matrix formats for linear algebra supporting scientific and machine learning applications, compatible with gonum matrix libraries. 
vectormath
Vectormath for Go, an adaptation of the scalar C functions from Sony's Vector Math library, as found in the Bullet2.79 source code. (currently inactive) 
triangolatte
2D triangulation library. Allows translating lines and polygons (both based on points) to the language of GPUs. 
ode
An ordinary differential equation (ODE) solver which supports extended states and channelbased iteration stop conditions. 
GoStats
GoStats is an Open Source GoLang library for math statistics mostly used in Machine Learning domains, it covers most of the Statistical measures functions. 
mudlarkgo
A collection of packages providing (hopefully) useful code for use in software using Google's Go programming language.

README
Gonum
Installation
The core packages of the Gonum suite are written in pure Go with some assembly.
Installation is done using go get
.
go get u gonum.org/v1/gonum/...
Supported Go versions
Gonum supports and tests on the two most recent Go releases on Linux, macOS and Windows.
Release schedule
The Gonum modules are released on a sixmonth release schedule, aligned with the Go releases.
i.e.: when Go1.x
is released, Gonumv0.n.0
is released around the same time.
Six months after, Go1.x+1
is released, and Gonumv0.n+1.0
as well.
The release schedule, based on the current Go release schedule is thus:
Gonumv0.n.0
: FebruaryGonumv0.n+1.0
: August
Build tags
The Gonum packages use a variety of build tags to set nonstandard build conditions. Building Gonum applications will work without knowing how to use these tags, but they can be used during testing and to control the use of assembly and CGO code.
The current list of noninternal tags is as follows:
 appengine — do not use assembly or unsafe
 safe — synonym for appengine
 bounds — use bounds checks even in internal calls
 cblas — use CGO gonum.org/v1/netlib/blas/netlib BLAS implementation in tests (only in mat package)
 noasm — do not use assembly implementations
 tomita — use Tomita, Tanaka, Takahashi pivot choice for maximimal clique calculation, otherwise use random pivot (only in topo package)
