Is there a sophisticated way of doing the following;
I have a vector = [ 1 ; 2 ; 3 ; 4 ; 6 ; 10 ; 3 ; 5 ; 3 ]
I would like to put this into another matrix so that; NEW MATRIX = [1 2 3; 4 6 10; 3 5 3];
Many thanks

data = rand(3);
result = reshape(data,3,3)';

B = reshape(A,m,n) or B = reshape(A,[m n]) returns the m-by-n matrix B whose elements are taken column-wise from A. An error results if A does not have m*n elements.

new = reshape(v,sqrt(length(v)),[]).'; % <-- The transpose is needed
