This is practice for implementing spline-interpolator

1. Dependency

OS

Linux(Ubuntu 18.04), QNX 6.5.0 SP

C++ Compiler

C++ version >= -std=c++03
gcc version >= 7.5.0
qcc : -Vgcc_ntox86_cpp

3rd party libraries

These libraries are used at unit_test.

googletest(>=1.8.1)
gnuplot( for unit_test )
