Hi,
Maybe you can check out sumsqr() which is a function that lets you find the sum of the squared vales of a matrix.
You can find it's documentation here. [https://www.mathworks.com/help/deeplearning/ref/sumsqr.html]
Just pass (sout - sin) to this and I think it should work.
Hope this helps.
Cheers.
