>>> help(N.bmat)
Help on function bmat in module numpy.core.defmatrix:

bmat(obj, ldict=None, gdict=None)
    Build a matrix object from string, nested sequence, or array.

    Ex:  F = bmat('A, B; C, D')
         F = bmat([[A,B],[C,D]])
         F = bmat(r_[c_[A,B],c_[C,D]])

        all produce the same Matrix Object    [ A  B ]
                                              [ C  D ]

        if A, B, C, and D are appropriately shaped 2-d arrays.
