A=[1 1;2 2;3 3;4 4;5 5;6 6;7 7;8 8;9 9;10 10;11 11;12 12;13 13]
B=[3;4;3;3]
C=[1;2;3;4;5;6;7;8;9;10;11;12;13]
for k = 1 : length(B)
if k == 1
row1 = 1
else
row1 = 1 + sum(B(1:k-1))
end
row2 = sum(B(1:k))
x{k} = A(row1:row2, :)
y{k}= C(row1:row2, 1)
end
%I wanna add (inv(x'*x)*x'*y) for each k into loop. Problem is x and y are cell in the loop.

Replace x by x{k}
inv(x{k}'*x{k})*x{k}'*y{k}

xc = mat2cell(A,B,size(A,2));
yc = mat2cell(C,B,size(C,2));
out = cellfun(@(a,b)(a'*a)\a'*b,xc,yc,'un',0);
