MATLAB: How to randomize the column position of a matrix

MATLABmatrix manipulation

suppose A=[D G H K … O];

i want to do C=[H D O …. G.. K]

i also want to keep the information about the order of randomization to use it other matrix further manipulation.

ind=randperm(size(A,2));
C=zeros(size(A));
C=A(:,ind);

ind preserves the order of randomization.

M = [1:100]';                  %Your matrix
M = M(randperm(size(M,1)),:);  %Your randomly permuted matrix by row

a=rand(3,3);
b=rand(100,3);
n=size(a,2);
m=size(b,1);
c=zeros(m,n);
for i=1:size(b,1)
 c(i,:)=a*b(i,:)';
end

%or simply

c=(a*b')'
