IF i have this matrix
A=[ 3 2 0
2 1 1
5 4 0
3 2 0
4 3 1
10 0 0 ]
and i found this matrix
a = [ 5
4
9
5
8
10 ]
and this matrix
b = [2
3
2
2
3
1 ]
i want to find this matrix F_Complete where for k=1:6 if (a(k) + b(k) - 1) == 10 then go back to A(k) and make group of ones depend on the number in the row(k) ( between each group there is zero ) like this
the third row in A = [5 4 0 ] make the condition true then
F_Complete(3,:) = [1 1 1 1 1 0 1 1 1 1]
the five row in A = [ 4 3 1 ] make the condition true then
F_Complete(5,:) = [1 1 1 1 0 1 1 1 0 1]
the last row in A = [ 10 0 0] make the condition true then
F_Complete(6,:) = [1 1 1 1 1 1 1 1 1 1]
then the final answer is
F_Complete = [ 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0
1 1 1 1 1 0 1 1 1 1
0 0 0 0 0 0 0 0 0 0
1 1 1 1 0 1 1 1 0 1
1 1 1 1 1 1 1 1 1 1 ]

Try this:
N = 10;
m = size(A,1);
% Pre-allocate the F_Complete matrix
F_Complete = zeros(m, N)
for i = 1:m
if a(i)+b(i)-1 == 10
tempVector = [ones(1,A(i,1)) 0 ones(1,A(i,2)) 0 ones(1,A(i,3))];
F_Complete(i,:) = tempVector(1:N);
end
end
Hope this helps!
