Unformatted text preview: 1 CS113 Introduction to Computing for Engineers Logical Operators and Conditional Statements 2 Programming in Matlab 3 Programming in Matlab 4 Programming in Matlab 5 Programming in Matlab 6 Programming in Matlab 7 Programming in Matlab 8 Programming in Matlab 9 Programming in Matlab 10 Programming in Matlab 11 Programming Example #1 1. Problem Definition Write a Matlab function file that computes the average grade based on a vector of test grades entered by the user. If the student did not pass the class (i.e. average grade < 60) then display the message The student did not pass the course. 2. Problem Analysis User Input: vector of numbers that represent test grades User Output: average test grade and message if the student did not pass the course Equations: Average = (sum of test grades) / (number of exams) 12 Programming Example 3. Develop Algorithm (processing steps to solve problem) Output to the user the average grade User inputs a vector of test grades. Assign that input vector the variable grades Determine the number of exams (Nexams) Compute the average grade AverageGrade=sum(grades)/Nexams Is Average<60? yes Display message Student failed the class! 12 Programming Example 3. Develop Algorithm (processing steps to solve problem) Output to the user the average grade User inputs a vector of test grades. Assign that input vector the variable grades Determine the number of exams (Nexams) Compute the average grade AverageGrade=sum(grades)/Nexams Is Average<60? yes Display message Student failed the class! no 13 Programming Example #1 function [ave_grade]=calc_grade(grades) % function [ave_grade]=calc_grade(grades) % This function computes the average grade for an input...
