Matlab Basics
Messin with Matrices
Matrix operations are the base by which we manipulate numbers and data in Matlab. This chapter serves as a one-stop reference for a wide range of fundamental syntax as you get familiar. Explore the examples and play with your own, use the snippet as a quick reference when you're programming, and before long this will all be second nature.
Task
- Defines the following two matrices as variables:
- Calculates the component-wise product of
A
andB
