Return vertices on perimeter of ellipse ROI object
v — Vertices
Vertices, returned as an n-by-2 matrix. The two columns define the x- and y-coordinates, respectively, of each of the n vertices.
Version HistoryIntroduced in R2007b
getVertices is not recommended
Starting in R2018b, a new set of ROI objects replaces the existing set of ROI objects. The new objects provide more functional capabilities, such as face color transparency. The new classes also support events that you can use to respond to changes in your ROI such as moving or being clicked. Although there are no plans to remove the old ROI objects at this time, switch to the new ROIs to take advantage of the additional capabilities and flexibility. For more information on creating ROIs using the new ROI functions, see Create ROI Shapes.
To retrieve the vertices of a new
ROI, access the value of the
Vertices property of the ROI.

This example creates an Ellipse ROI and uses
imshow('cameraman.tif') h = imellipse(gca,[10 10 100 100]); v = getVertices(h)
Here is equivalent code, creating a new
imshow('cameraman.tif') h = drawellipse(gca,'Center',[60,35],'SemiAxes',[50,25]); v = h.Vertices
