Question

O Fit to page ID Page vi Programming assignment 6 Assume that the following student information is stored in a MATLAB structure student student name contains the full name of the student student..pa contains the GPA of the student student.standing contains whether the student is in good academic standing (true/fake) Write a function update(student, field, value) that does the following: Thes as an input a student structure, a student field name, and a value Epla 2. Returns a student structure where the value for the corresponding field name is updated to 3. If the input for the student field name is incorrect, the function should notify the water and leave the structure unchanged. pts 4. If the data type of the value is incorrect, the function should notify the user and leave the structure unchanged Create a student structure by typing the following in your command window >> test student struct('name', 'Mary A. Smith', 'pa', 3.21, 'standing':true) Then test your funetion with the following: (2 pts) >> updated student update(test student, 'name','Mary A. Joht updated student name: 'Mary A. Johnson pa 3210000000000000 landing: 1 >> updated student updates student,'spa', 3.4) updatulatudent

Answer 1

function student = update(student,field,value)

if ~isfield(student,field)

disp([field,' is not a field of student!'])

elseif strcmp(field,'name') && ~ischar(value)

disp('name should be a character vector')

elseif strcmp(field,'gpa') && ~isnumeric(value)

disp('gpa should be a number')

elseif strcmp(field,'standing') && ~islogical(value)

disp('standing should be a logical value')

else

student.(field)=value;

end

COMMAND WINDOW >> test student struct('name', 'Mary A. Snith', 'gpa', 3.21, 'standing', true) test_student = struct with fields: name: 'Mary A. Snith' gpa: 3.2100 standing: 1 >> update_student=update(test_student, 'name', 'Mary A Johnson') update_student = struct with fields: name: 'Mary A Johnson' gpa: 3.2100 standing: 1 >> update_student-update(test_student,'name1', 'Mary A Johnson') name1 is not a field of student! update_student = struct with fields: name: 'Mary A. Snith' gpa: 3.2100 standing: 1
