Q = randi(456,10,15);
row=[1 2 5 4 3 6];
column=[5 7 3 4 8 14];
p = Q(row,column);
P = zeros(size(Q));
P(1:numel(row),1:numel(column)) = p;
The problem is:
I need matrix p to have Q(row(1),column(1)), Q(row(1),column(1)), Q(row(2),column(2)), Q(row(3),column(3)), Q(row(4),column(4)), Q(row(5),column(5)), and Q(row(6),column(6)). But what (p = Q(row,column);) give me is a 6*6 matrix in this way Q(row(1),column(1)), Q(row(1),column(2)), Q(row(1),column(3)), Q(row(1),column(4)), and..... How can solve this problem?
