sygma notation for equation

Hello everyone

I am trying to compute a sigma summation of a simple row vectors, where:

i= 0:10:200

sin= 0:0.1:1;

sout=inv(D*LTL+ID)*D*LTt

and I need to solve E from :

help is hugely appreciated. Many thanks

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.
