How do I Measure Distances in an Image and save them in an array?

Hi,

I have a question regarding the script resented here:

https://se.mathworks.com/help/images/measure-distances-in-images.html

After I have measured a few features and created labels, how do I save them in an array for future use?

I take it is should be the "diffPos" variable in the function Update Units? Help would be much appreciated.

Thanks in advance!

I haven't been able to test this out but you should be able to change the output argument to include diffPos:

function diffPos = updateUnits(src,evt)

Alternatively, you may be able to save the data to a mat file using the save function (put this line at the end of the updateUnits function):

save('diffPosData.mat','diffPos')

You will then be able to load the file back into MATLAB using load.
