Question

Task 2 Download the ENG1060studentmarks.txt file from the Moodle. The file contains the following information: 1. Column 1: Student ID 2. Column 2--11: Lab marks (/10) worth 2% each (20% total of final grade) 3. Column 12: Assignment mark (/10) worth 10% of the final grade 4. Column 13: Exam mark (100) worth 70% of the final grade a) Write a function that accepts a student's laboratory, assignment and exam marks as inputs to determine the final mark to the nearest integer and the letter grade of the student. Your function header would be similar to: function (final_mark, grade) = markscalc(lab, assignment, exam) Note: The letter grades should be stored as a 'string' and are described as follows: final_mark 2 80 → HD 70 s final_mark < 80 → D 60 s final_mark < 70 → 50 s final_mark < 60 → P final_mark < 50 → F b) Write an m-file that achieves the following: 1. Prompts the user to input a student's ID number and extracts the individual assessment marks from the ENG 1060studentmarks.txt file. 2. Use the function written in part a) to calculate the student's final mark and letter grade. Hint: You may want to use logical statements or the find() command to determine the row of the ID number which was input by the user.

Matlab question

Answer 1

Working code implemented in Matlab and appropriate comments provided for better understanding:

Here I am attaching code for these files:

• getmarks.m
• Task2.m

Source code for getmarks.m:

% Function for Task 2 : Final Marks
%
%
%INPUTS
%lab_m = total marks for lab
%ass_m = total assignment marks
%oth_m = total other marks
%exm_m = total exms marks
%
%
%OUTPUTS
%Final_m = final marks
%grade = final grade
%
%
%defines the function getmarks with 4 input arguments
%this function returns two values
function [ final_m, grade ] = getmarks(lab_m , ass_m , oth_m , exm_m)

%calculates the final marks of student
final_m = (0.25*(lab_m/100) + 0.1*(ass_m/10) + 0.15*(oth_m/15) + 0.5*(exm_m/100))*100;

%if else statement to determine which grade category the student belongs to
if final_m >= 80
  
grade = 'HD';
  
elseif final_m >= 70
  
grade = 'D';
  
elseif final_m >= 60
  
grade = 'C';
  
  
elseif final_m >= 50
  
grade = 'P';
  
else
  
grade = 'N';
  
end

% Task 2 : Final Marks
close all; clear all; clc;

%prompts the user for their student ID
usr_id = input('Welcome to Monash, please enter your student ID :');

%imports the data from ENG1060studentmarks.txt into a table

%gets the numeric data values in the form of a matrix
marks_table = datum.data;

%finds the row of where the inputted student id is
[ x, y ]= find(marks_table == usr_id);

%sums up the lab marks (column 2 to 11)
lab_total = sum(marks_table(x,2:11));

%gets the marks for assignment, others and exm
ass_total = marks_table(x,12);
oth_total = marks_table(x,13);
exm_total = marks_table(x,14);

%calls the function getmarks with the 4 in put arguments above
%function reutrn 2 values
[ total_marks, grade ] = getmarks(lab_total,ass_total,oth_total,exm_total);

%prints the final mark and grade
fprintf('your total mark is %3.0f, your grade is ',total_marks);
fprintf(grade);
