InSPIRE utility to plot a 2D displacement field

This program plots the deformation field (displace vectors) contained in vector.txt.

This producted by ITK image registration programs. Check the ITK output format of the registration program you are using and modify the fscanf line accordingly. NOTE the demonstration figure was plotted by replacing the zero vectors z1
%and z2 by:
z1 =0 0 0 0 0 1 2 3 4 0 0 0
z2 =0 0 0 0 0 1 1 0 0 0 0 0
once the vector.txt read into the workspace, manually change the z1 and z2
to the above vectors to get the figure. The z vector was separated into
its x and y components.
