I want to evaluate a function Least_square(), over multiple iterations and return its sum. I am currently doing this by
fun = @(x) ( Least_square(x,y1) + Least_square(x,y2) + Least_square(x,y3) + Least_square(x,y4) )
Is there a better method to do this? Since I may want to evaluate it over multiple iterations
Thanks

Do not understand what you want. What are x.Nd and x.mD1? It does not look like you are changing the inputs to your function.

y = [y1, y2, y3, y4]
fun = @(x) reshape(sum(arrayfun(@(Y) Least_square(x(:), Y), reshape(y, 1, [])),2), size(x))

In the case that you know that Tvalues and so on are row vectors, then you can leave out the (:).'
