Indexing into Structures

Hi,
I currently have an array of structures that have fields whose values are also arrays. I am trying to grab one column of data from every single structure in matlab...
the statement I use to do this is the following
structName(:).fieldName(:,1)
However this isn't grabbing the first column of the value fieldName from ALL structures. I'm only getting a single array of data and not the twenty that I should normally be getting, because there are twenty structures.
Am I missing something here or is this a limitation of Matlab?

Are all of fieldName the same size? Do they all have the same number of rows? If so then there some simplifications that can be made.
To give an answer, though, we need to know what output datatype and shape you are looking for.

Each value in fieldName is 20x51, and you want to take the first column of each, so that would be 20x1 for each. You want the result to be 20x51. Is the implication that your structure array has 51 elements and you want the second dimension index to be the same as the structure array index? Or is the 20x51 desired result somehow related to the fact that each fieldName is 20x51, even though you only want the first column of each fieldName ?
