Help with matrix manipulation

I'm trying to do 2D rotations using matrices but don't know how to format it to return a 2x3 matrix.

%%Rotation Matrix for platform

% angle in degrees
THETA = 90;

% Matrix
R = [ cosd(THETA), -sind(THETA);
      sind(THETA), cosd(THETA) ];

for i=1:3
    rotated{i} = R * [ x(i); y(i) ];   
end

The result I get is an array:

rotated = 

    [2x1 double]    [2x1 double]    [2x1 double]

However my desired result is the matrix =

rotated =
  [x1]    [x2]    [x3]
  [y1]    [y2]    [y3]

Can any shed some light on this problem for me please?

cell2mat(rotated)

?

[Ian Phillips]

rotated = cell2mat(rotated);

This worked, thanks.
