determine the loop which satisfies the particular condition.

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]

%I need to create this loop w.r.t A and B.

x1=A(1:B(1),:) 
x2=A(B(1)+1:B(1)+B(2),:)
x3=A(B(1)+B(2)+1:B(1)+B(2)+B(3),:)
x4=A(B(1)+B(2)+B(3)+1:B(1)+B(2)+B(3)+B(4),:)

I hope this wasn't your homework (taking you at your word since you did not tag it as homework) because it looks like it.

clc;
workspace;

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]

% I need to create this loop w.r.t A and B.

x1=A(1:B(1),:) 
x2=A(B(1)+1:B(1)+B(2),:)
x3=A(B(1)+B(2)+1:B(1)+B(2)+B(3),:)
x4=A(B(1)+B(2)+B(3)+1:B(1)+B(2)+B(3)+B(4),:)

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, :)
end

no it doesn't my homework

x = mat2cell(A,B,size(A,2))
