## 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.
