Simple calculations and graphs

In this section, I will give a quick introduction to defining numbers, vectors and matrices in Matlab, performing basic computations with them, and creating simple graphs. All of these topics will be revisited in greater depth in later sections.

• Entering vectors and matrices; built-in variables and functions; help
• Graphs
• Arithmetic operations on matrices
  • Standard operations
  • Solving matrix equations using matrix division
  • Vectorized functions and operators; more on graphs
• Some miscellaneous commands
