Overview

Package vlib gonum.go friendly C and R vectors Based on gonum/examples - This example shows how simple user types can be constructed to implement basic vector functionality within the mat package.

Helps interface plotter XYers with vlib library routines

Package vlib provides some trivial functions for vector of int,float64,complex128 and bits. Each corresponding vector is extended from the standard array of data types. Hence it can be type-casted anytime and interface with other libraries
