4. Machine precision: (a) Write a matlab program to find the machine precision Emach of your computer based on the following definition: The machine precision is the smallest number such that fl(1 + ) > 1. (b) Use the same program (with some parameter changes) to find the smallest positive number Imin that can be represented in your computer. Do not use any built-in functions of matlab, i.e., use only addition, subtraction, multiplication, and division for calculations.
