How to insert a matrix to another matrix ?
Show older comments
i have a 5 by 1 matrix A=[1,2,3,4,5] Now there is another matrix B say 5 by 5 matrix. i want matrix A to insert into matrix B such that matrix A's 1st column still has the values 1,2,3,4,5 and the rest of the columns will have the values of matrix B.
Thanks in advance

A = [1,2,3,4,5];
B = randi(5,5);
Your A is a row vector, not a column. You can use transpose A'
C = [A' B]
C =
1 3 4 3 5 1
2 1 5 1 3 1
3 3 4 2 5 4
4 5 4 2 4 3
5 1 2 2 2 5

Your question is little unclear. If you want Matrix B's first column replaced by A then,
A is 5X1 B is 5X5
B=[A B(:,2:end)]

A = (1:5)'
B = randi(25,5);
B(:,1) = A;
