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.

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.
