GETFIELD Get Field Contents

Section: Elementary Functions

Usage

Given a structure or structure array, returns the contents of the specified field. The first version is for scalar structures, and has the following syntax 
   y = getfield(x,'fieldname')

and is equivalent to y = x.fieldname where x is a scalar (1 x 1) structure. If x is not a scalar structure, then y is the first value, i.e., it is equivalent to y = x(1).fieldname. The second form allows you to specify a subindex into a structure array, and has the following syntax 

    y = getfield(x, {m,n}, 'fieldname')

and is equivalent to y = x(m,n).fieldname. You can chain multiple references together using this syntax.
