Hi

It is a little bit tricky but follow the steps;

1) Create a matrix to hold the values of A=[1 2 3 4 5 6]'
     C=zeros(3,2)

2) initialize a variable named k=0

3) then write the following program

for i=1:3
for j=1:2
C(i,j)=A(k+i+j-1)
end
k=k+1
end

then it works :)

Regards

A=[1 2 3 4 5 6]
B=reshape(A,3,2)

if A has any even length then
B=reshape(A,[],2)
