add collum to one matrix from another

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),

[Stephen23]

Please show us the expected output.

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.
