hello
i have two arrays
#of shape (1,6)
eval=array([[3.,3.2,1.,1.1,5.,0.5]])

#of shape (6,8)
egimgs=array([
		 [3.,2.,1.,4.,5.,1.5,2.5,1.1],
		 [1.1,3.,.5,.2,.1,4.3,3.2,1.2],
		 [4.,3.,2.,6.,1.,4.,5.1,2.4],
		 [3.2,1.3,2.2,4.4,1.1,2.1,3.3,2.4],
		 [.4,.2,.1,.5,.3,.2,1.2,4.2],
		 [5.2,2.1,4.3,5.5,2.2,1.1,1.4,3.2]
		 ]
	    )

i need to multiply the first row of egimgs with the first element of
eval , second row of egimgs with second element of eval ..etc ...and
so on..finally i should get a result array of same shape as egimgs.
how should i proceed ? using  loops seems inefficient.can someone
suggest a better way?

thanks
W
