Create Structure Array

This example shows how to create a structure array. A structure is a data type that groups related data using data containers called fields. Each field can contain data of any type or size.

Store a patient record in a scalar structure with fields不结盟运动e,billing, andtest.

patient(1).name ='John Doe'; patient(1).billing = 127.00; patient(1).test = [79, 75, 73; 180, 178, 177.5; 220, 210, 205]; patient

patient =结构体with fields:不结盟运动e: 'John Doe' billing: 127 test: [3x3 double]

Add records for other patients to the array by including subscripts after the array name.

patient(2).name =“安巷”; patient(2).billing = 28.50; patient(2).test = [68, 70, 68; 118, 118, 119; 172, 170, 169]; patient

patient =1x2 struct array with fields:不结盟运动e billing test

Each patient record in the array is a structure of class结构体. An array of structures is often referred to as a struct array. Like other MATLAB arrays, a struct array can have any dimensions.

A struct array has the following properties:

Any unspecified fields for new structs in the array contain empty arrays.

patient(3).name ='New Name'; patient(3)

ans =结构体with fields:不结盟运动e: 'New Name' billing: [] test: []

Access data in the structure array to find how much the first patient owes, and to create a bar graph of his test results.

amount_due = patient(1).billing

amount_due = 127

标题栏(病人(1)test) (['Test Results for ', patient(1).name])
