## 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 syntaxy = 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.
