Retrieving only one field in a struct

I have an array of X=1*1 sturct with 4 fields.

x has the value of 1*726 double

y has the value of 1*656 double

z has the value of 656*726 int16

info has the value of 1*1 struct

These data are from a satellite.hdr image that I used the 'enviread' command to read them. I want to retrieve only the z field since it has the values that I need. I used

value = getfield(X,z);

but it does not show only the z field values.

How can I solve this please?
