I need to initiate a matrix, like this:
SQ = diag ( sequare root(sqrt(S(l,:))-segma), sequare root(sqrt(S(2,:))-segma)......sequare root(sqrt(S(9,:))-segma),0)
But not sure how to do this in Matlab, my code is here, and I stopped at SQ line, I put a loop from 1 to 10 for j, but not sure how to do the rest of this Matrix
function [B] = FD(A,l)
[n,d] = size(A);
B = zeros(10,d);
B(1:9,:) = A(1:9,:);
for i=10:1125,
B(10,:) = A(i,:);
[U,S,V] = svd(B);
segma = sqrt(S(10,:));
for j=1:10,
SQ= diag ......

Please provide an example of the matrix you want to create and the data you want to use from which you want to create it. It is not at all clear from the code you have provided.
What does the ‘sequare root’ function produce? We have absolutely no idea.
