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

在 MATLAB Online 中打开

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
