length of a boundary segment
Syntax
[x,y] = intersect(gB,xy1,xy2)
[x,y,segLength] = intersect(gB,xy1,xy2)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'),'minPixel',3)
grains = smooth(grains,4)
plot(grains.boundary,'micronbar','off')
% define some line
xy1 = [33500,4500]; % starting 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','linewidth',2)ebsd = EBSD (y↑→x)
