I want to add b33, b23, b11 to matrix a between first and second collum
A=[3 7 13;-8 -3 -4; 6 8 17]
B=[6 -4 -3; -11 14 -12;-15 12 -2]
C= A(:,1),

B(3,3), B(2,3), B(1,1) don't constitute a column from B.
C is a column from A.
We have two arrays A and B, and two vectors. What goes where?

Hi,
You can create a column vector from b33, b23 and b11 which refer to third element of the third column of matrix B, second element of the third column of matrix B and first element of the first column of matrix B respectively.
Then this column vector can be easily added between the first and second columns of A.
I am attaching a code snippet for your reference.
ColumnVec = [B(3,3);B(2,3);B(1,1)]; % assuming order is b33, b23 and b11
A_new = [A(:,1),ColumnVec, A(:,2:end)];
I hope it addresses your query.
Regards,
Zuber
