MATLAB: MATLAB function for reordering the matrix rows and columns as desired

matlab functionreordering matrix

Hi all,

Suppose I have a nxn matrix ordered row-wise as well as column-wise as 1,2,3…10 (say n=10). Now if I wish to reorder the columns of this matrix as per the order [2 6 1 7 9 3 4 5 10 8], is there a MATLAB function readily available for the task?

Regards,

A(:,[2 6 1 7 9 3 4 5 10 8])

Easy ;-)

MATLAB: Reordering the data

What about generating two random numbers as indices and swapping the data of the indices? And then do this in a loop.

clc
D=[1 2 3 4 5 6 7 ]
for k=1:10
    x1=randi(length(D));
    x2=randi(length(D));
    dummy=D(x1);
    D(x1)=D(x2);
    D(x2)=dummy
end
