(b) The following code is for calculating and plotting engineering stress and strain in a typical tension test. Find at least four errors in the code. For each error identified, explain why the error is caused.

Suppose the rate is 9% if the amount in your savings account is less than $5000, 12% for balances of $5000 or more but less than $10,000 and 15% for balances of $10,000 or more. If you have $15000 in your account, write a MATLAB program to calculate your new balance after one year, after you have received the interest. (20 marks)
