hi. i have two variables which are AREA and PERIMETER.

how to save both variables in a mat.file? i only have coding for one variable only :

   _ _ _objArea = objMeasurements(k).Area;      % Get area.
   AREA=[objArea;AREA];
  save('AREA.mat','AREA');

objPerimeter= objMeasurements(k).Perimeter;        % Get perimeter.
PERIMETER=[objPerimeter;PERIMETER];
save('PERIMETER.mat','PERIMETER');___

Save all the variables into a single matrix. Then you can save it as a Mat

Answer 1

save(Filename, 'AREA', 'PERIMETER')

i already tried it. but it only save in MAT.file but different folder. i want AREA and PERIMETER together in two column in one MAT.file.For example, 14X2.

You can specify a folder name when you save().

To save both values as columns in a single variable:

AREA_PERIMETER = [AREA, PERIMETER];
save(Filename, 'AREA_PERIMETER');

You could do this in two calls:

save(filename,'AREA')
... other code
save(filename,'PERIMETER','-append')

OR in one call:

save(Filename, 'AREA', 'PERIMETER')
