Last Notes on MATLAB Introduction

  • It is very easy to handle complex numbers in MATLAB. The special value i and j stand for √-1, try sqrt(-1) to see how MATLAB represents the complex numbers.
  • Input statement can be used to make your program more interactive and easy to compile, so basically you make your program in a way that it will ask the user to enter certain values and then work on those values.
