length of a boundary segment
Syntax
Input
gb | grainBoundary |
xy1, xy2 | coordinates of the endpoints of the line |
Output
x,y | list of intersection points |
Example
mtexdata small grains = calcGrains(ebsd('indexed')) grains = smooth(grains,4) plot(grains.boundary,'micronbar','off') % define some line xy1 = [33500,4500]; % staring point xy2 = [36000,7500]; % end point line([xy1(1);xy2(1)],[xy1(2);xy2(2)],'linewidth',1.5,'color','g') [x,y] = grains.boundary.intersect(xy1,xy2); hold on scatter(x,y,'red')
% find the number of intersection points sum(~isnan(x)) % mark the intersected boundary segments plot(grains.boundary(~isnan(x)),'lineColor','b','linewidth',2) hold off
