S =

1×2 struct array with fields:

X

map

caption

For nonscalar structures, the syntax for accessing a particular field is

structName(indices).fieldName. Redisplay the clown image, specifying the index

for the clown struct ( 1 ):

image(S(1).X)

colormap(S(1).map)

Add indices to select and redisplay the upper left corner of the field contents:

upperLeft = S(1).X(1:50,1:80);

image(upperLeft)

NoteYou can index into part of a field only when you refer to a single element of a

structure array. MATLAB does not support statements such as S(1:2).X(1:50,1:80),

which attempt to index into a field for multiple elements of the structure.
