MATLAB: Add a field to structure

Question

Sat1=regionprops(MaskIm, {'Area', 'Eccentricity', 'EulerNumber', 'MajorAxisLength', 'MinorAxisLength', 'Orientation', 'Perimeter'});

How to divide MajorAxisLength with MinorAxisLength and then add it to Sat1 structure under 'AspectRatio' name?

Answer 1

MaskIm = imread('text.png');
Sat1=regionprops(MaskIm, {'Area', 'Eccentricity', 'EulerNumber', 'MajorAxisLength', 'MinorAxisLength', 'Orientation', 'Perimeter'});
AR = [Sat1.MajorAxisLength]./[Sat1.MinorAxisLength] ;
[Sat1.AspectRatio] = deal(AR) ;
