I have the 1x9 vector [5 3 2 6 7 26 4 33 3]
I want to obtain the matrix [5 3 2; 6 7 26; 4 33 3] using completely vectorized code. How can this be done?
As a start, I have vectorized code to build the 3x3 matrix [ 1 2 3; 4 5 6; 7 8 9], so that the values are the vector columns, but I don't know how to do the vectorized referencing.
Thanks

A= [5 3 2 6 7 26 4 33 3]
out= reshape(A,3,[])'
