vector multiplication and dot product

i have 2 matrix and i want to do matrix multiplication, but the elements in matrix are vectors, so i want to take dot product of the elements, can u suggest me a way...

q=[a b;c d]*[e f]

where

a=[1 2 3]=b=c=d=e=f

the output will be [a.e+b.f ; c.e+d.f]

and expected output is [28;28]

please suggest a good way to tackle this problem

Please post the matrix q in valid Matlab syntax. It is not clearly defined yet. Do you mean this:

q = [1,2,3,1,2,3; ...
     1,2,3,1,2,3]

[pravin behera]

    q=[(1 2 3) (1 2 3); (1 2 3)  (1 2 3)] * [(1 2 3) ; (1 2 3)]
     =[ (1 2 3).((1 2 3) + (1 2 3).(1 2 3)  ; (1 2 3).((1 2 3) + (1 2 3).(1 2 3)]
     =[14+14 ;14+14]
     =[28;28]

this is what i want to do

You cannot have the grouping q = [(1 2 3) (1 2 3); (1 2 3) .... for ordinary matrices, but you can do this:

   [1 2 3 1 2 3;1 2 3 1 2 3]*[1 2 3 1 2 3].'

where ".'" denotes the transpose and the result will be [28;28].
