From a matrix how can I randomly select one column combination at a time

Suppose I have

A = [ 1  0  0
      0  1   1
      1   1   0]

I would like to get any column based on value of a random number, and send to another matrix with the other two columns successively.

This will do it:

A = [ 1  0   0
      0  1   1
      1  1   0]
[rows, columns] = size(A)
% Get a random column.
randomColumn = randi(columns)
% Get indexes of the other columns.
otherColumns = setdiff(1:columns, randomColumn)
% Take that random column, and tack on the other columns to the right of it.
outputMatrix = A(:, [randomColumn, otherColumns])

For example:

A =

1 0 0

0 1 1

1 1 0

randomColumn =

2

otherColumns =

1 3

outputRowVector =

0 1 0

1 0 1

1 1 0
