how can I access lower level structure arrays without a loop?

I have a structure defined (S) that is 1xM structure, where S.geo.xy = Nx2 matrix

so disp(S(1).geo.xy) returns

    0.4150   -0.1935
    0.4150    0.1935
    0.5850    0.1935
    0.5850   -0.1935

I want to take all M in the S structure and concatenate the values to one vector without using a for loop. I can easily do this with a for loop. But I was looking for a more efficient way. For example in the structure I have another field that is S(1).anyfield

ans =

    6.1700         0

and I can pull all these values into one vector by typing [temp.anyfield] and reshaping for a matrix. But [temp.geo.xy] doesn't work the same. Any thoughts?

Thanks for the help, John

Do you want to concatenate s.geo.xy with s.anyfield?

No, I was just using s.anyfield as an example of how I can concatenate s.anyfield without a loop but it doesn't work the same for s.geo.xy
