Hello,
I am trying to learn MATLAB and decided to use the MIT course to look at the slides and I figure the homework would be challenging so I decided to do that as well. I am stuck on problem 9.G.iii. Can someone please assist me.
Here is my code
clear all, close all, clc%b
load classGrades%c
namesAndGrades%d
grades = namesAndGrades(:,2:end)%e
meanGrades = nanmean(grades(:,1))for i = 1:7 meanGrades(i,:) = nanmean(grades(:,i))end[gradesRows, gradesCol] = size(grades)%f
for i = 1:15 meanMatrix(i,:) = meanGradesendcurvedGrades = 3.5*(grades./meanMatrix)checkCurvedGrades = nanmean(curvedGrades);%f.iv
curvedGrades5 = find(curvedGrades > 5)for i = curvedGrades5curvedGrades(i) = 5endcheckCurve = find(curvedGrades == 5)tf = isequal(curvedGrades5,checkCurve)%g
totalGrade = nanmean(curvedGrades')totalGrade = ceil(totalGrade)letters = ['F','D','C','B','A'];findF = find(totalGrade ==1);findD = find(totalGrade ==2);findC = find(totalGrade ==3);findB = find(totalGrade ==4);findA = find(totalGrade ==5);
