Column and row rearrangement

How to rearrange column and row matrix?For example, I have 10x10 matrix size. I want to move the 10th column and row into 1st column and row.Then,1st column and row will move to 2nd column and row. 2nd row and column will move to 3rd column and row. And also, repeat for next column and row.

Use the circshift function. With it, you can do everything you seem to describe wanting to do with your matrix.

Ok.Noted.Success.After complete the 1st loop of movement, how to move 8th column and row into 1st column and row but 9th column and row remain at the same position.

Good.

This seems to do what you want:

M = randi(99, 10)                                   % Create Matrix
M2 = circshift(M(1:8,1:8), [1 1]);                  % Select Submatrix & ‘circshift’ Rows & Columns
M(1:8,1:8) = M2                                     % Substitute Shifted Matrix Back Into Original

Ok.Noted. I have tried the code.It success to move the column and row that I want but, the matrix size is reduced.The original matrix size is 10x10, but at final it only had 6x6. Let me rephrase, what I really want to do:-

K[1:10,1:10] %original position of column & row matrix size

K2[2 4 6 8 10 1 3 5 7 9,2 4 6 8 10 1 3 5 7 9] %New arrangement of column and row position in matrix

Hope you can help me.

When I ran my code (and I just ran it again to be sure), the final ‘M’ matrix size was (10x10) and the (8x8) submatrix rows and columns were correctly rotated and correctly inserted back into the original (10x10) ‘M’ matrix when I examined it. I don’t understand how you got a (6x6) matrix with my code.

I’m not certain what you want as your result, but this looks correct to me:

K = randi(99,10)
K2 = K([2 4 6 8 10 1 3 5 7 9]',[2 4 6 8 10 1 3 5 7 9]')

You have to transpose the row and column reference vectors.
