MATLAB Student Information

MATLAB Code

Answer:
clear

% Create a structure for student information
studentinfo = struct('first','Homer','middle','James','last','Kiaei','IDnumber',12345,'GPA',4.0);

% display
disp( studentinfo );

Expected Output

  struct with fields:

        first: 'Homer'
       middle: 'James'
        last: 'Kiaei'
    IDnumber: 12345
         GPA: 4

Code Explanation

This MATLAB code demonstrates how to create and display a structure variable that stores student information with multiple fields of different data types.

Step 1: Clear Workspace

The clear command removes all variables from the workspace, ensuring a clean environment.

Step 2: Create Structure

The struct function creates a structure named studentinfo with field-value pairs for student data.

Step 3: Display Structure

The disp(studentinfo) command displays the entire structure with all its fields and values.

Structures in MATLAB are useful for organizing related data elements together, making the code more readable and maintainable.

Structure Field Details

Field Name	Value	Data Type	Description
first	'Homer'	char array	Student's first name
middle	'James'	char array	Student's middle name
last	'Kiaei'	char array	Student's last name
IDnumber	12345	double	Student's identification number
GPA	4.0	double	Student's grade point average

Accessing Structure Fields

You can access individual fields of the structure using dot notation:

% Access individual fields
firstName = studentinfo.first;
studentID = studentinfo.IDnumber;
gpaValue = studentinfo.GPA;

% Display specific fields
fprintf('Student: %s %s %s\n', studentinfo.first, studentinfo.middle, studentinfo.last);
fprintf('ID: %d, GPA: %.1f\n', studentinfo.IDnumber, studentinfo.GPA);
