octave-gmt binary package in Ubuntu Trusty arm64

 GMT is a collection of tools that allow users to manipulate
 (x,y) and (x,y,z) data sets (including filtering, trend fitting, gridding,
 projecting, etc.) and produce Encapsulated PostScript File (EPS) illustrations
 ranging from simple x-y plots through contour maps to artificially illuminated
 surfaces and 3-D perspective views in black and white, gray tone, hachure
 patterns, and 24-bit color.
 .
 This package provides an interface for GNU Octave to query and read/write
 GMT grid files.
