After completing the activities in this module, you will be able to
- Access and open MatLab
- Enter data sets on Matlab in the form of Matrices
- Perform simple mathematical operations using Matlab
- Plot data using Matlab
- Run a custom scripts using Matlab
Matlab is an interactive software package for scientific and engineering numeric computation. The name Matlab stands for matrix laboratory. Matlab works using essentially only one kind of object, a rectangular numerical matrix. In some situations, special meaning is attached to 1-by-1 matrices, which are scalars, and to matrices with only one row or column, which are vectors. Problem solutions are expressed in Matlab almost exactly as they are written mathematically - with no programming required.
In this laboratory course you will use Matlab to perform data analysis. The purpose of this activity is to review the basics of using Matlab and to show you a little of the power and graphics capability of this package.
