Building structure arrays using assignment statements

You can build a simple 1-by-1 structure array by assigning data to individual

fields. Matlab automatically builds the structure as you go along. For

example, create the 1-by-1 patient structure array shown at the beginning of

this section [2]:

“patient.name = 'John Doe';

patient.billing = 127.00;

patient.test = [79 75 73; 180 178 177.5; 220 210 205]; “

and if you type: “patient” in the command window you get:

“patient =

name: 'John Doe'

billing: 127

test: [3x3 double] ”

that is an array containing a structure with three fields. To expand the

structure array, add subscripts after the structure name:

“patient(2).name = 'Ann Lane';

patient(2).billing = 28.50;

patient(2).test = [68 70 68; 118 118 119; 172 170 169];”

and if you again type: “patient” you will get:

“patient =

1x2 struct array with fields:

name

billing

test ”

The patient structure array now has size [1 2]. Note that once a structure

array contains more than a single element, Matlab does not display

1 2 ... 86 87 88 89 90 91 92 93 94 95 96 ... 118 119
