  2. EXAMPLE Write a script file that determines the balance in a saving account at the end of every year for the first 10 years. Initial investment of $1,000 and interest rate of 6.5% compounded annually. Display the information in a table. For an initial investment of A, and interest rate of r, the balance B after n years is given by:

  3. SOLUTION Referenced in first MATLAB lecture format bank yr = [1:10]; % Creating a vector of year numbers. balance = 1000*1.065.^yr; % Creating a vector of the balance. table_yr_blnc(:,1)=yr'; % Substituting the yr vector in the first column of the table matrix. table_yr_blnc(:,2)=balance'; % Substituting the balance vector in the second column of the table matrix. disp(' YEAR ACCOUNT') % Display titles. disp(' BALANCE ($)') % Display titles. disp(' ') % Display an empty line. disp(table_yr_blnc) % Display the table.

  4. SOLUTION Executing the script file in the command window gives: >> Lecture4Example4 YEAR ACCOUNT BALANCE ($) 1.00 1065.00 2.00 1134.22 3.00 1207.95 4.00 1286.47 5.00 1370.09 6.00 1459.14 7.00 1553.99 8.00 1655.00 9.00 1762.57 10.00 1877.14

  5. ASSIGNMENT 5: • 1. Problem 32 page 61 in the textbook. • Problem 33 page 61 in the textbook. • Problem 4 page 161 in the textbook. For each problem write a script file and execute it in the command window. For each problem, the first two lines of the script file are: % Assignment 5, Problem (write the number of the problem) % Name: (first name, last name) Submit a printout of the script file, and a printout of the command window.
