MATLAB® and Its Applications in Engineering: [Based on MATLAB 7.5 (R2007b)]

5.2. Data Input

The fundamental data-type in MATLAB is array. It encompasses several distinct data objects—integers, doubles (real numbers), matrices, character strings, structures and cells. There is no need to declare variables as real or complex. When a real/complex number is entered as the value of a variable, MATLAB automatically sets the variable to be real/complex. There are three common ways to input data in MATLAB:

1.	Assign data to different variables through an assignment statement.
2.	Input data from keyboard as per commands displayed on the monitor.
3.	Read data from a file, which has been already stored in the computer’s memory.
