Extract a row from matrix

laser — Thu, 12 Jul 2007 04:20:22 -0400

suppose we have 3*3*3 dimension matrix A, and A(10,:,:) =

0 0 0
1 2 3
0 0 0

I wnat to plot the second row, I can't direct use A(10,2,:), since
it's 1*1*3 dimension. So I need to extract the row to a 1*3 dimension
array. How can I do that? thanks.
