Overview ¶
Gonum is a set of packages designed to make writing numerical and scientific algorithms productive, performant, and scalable.
Gonum contains libraries for matrices and linear algebra; statistics, probability distributions, and sampling; tools for function differentiation, integration, and optimization; network creation and analysis; and more.

Functions ¶
func Version ¶
func Version() (version, sum string)
Version returns the version of Gonum and its checksum. The returned values are only valid in binaries built with module support.
If a replace directive exists in the Gonum go.mod, the replace will be reported in the version in the following format:
"version=>[replace-path] [replace-version]"
and the replace sum will be returned in place of the original sum.
The exact version format returned by Version may change in future.
