matrix multiplication

Hi all
i have
w1 =
    1.0000    1.0000    1.0000    1.0000    1.0000    1.0000    1.0000    1.0002    1.0000    1.0001    1.0000    1.0001
I want a new matrix with product of all terms in each 2×2 matrix in w1
Eventually, I need a 1×3 matrix.
If I use prod(w1), only the columns get multiplied.
Can anyone help please

• blkproc(w1,[2 2],@prod)
