## Entering Commands

This example shows how to enter basic commands in MATLAB.

To create and process variables, use the assignment operator '='.

```disp('Assign value to variable m:') disp('>> m = 2*1.5') m = 2*1.5 ```
```Assign value to variable m: >> m = 2*1.5 m = 3 ```

A semicolon ';' to the end of a command suppresses the output.

```disp('Add semicolon to suppress output:') disp('>> m = 2*1.5;') m = 2*1.5; ```
```Add semicolon to suppress output: >> m = 2*1.5; ```

To conditionally execute statements, use the 'if', 'elseif', and 'else' statements.

```disp(' ') disp('Check value of m:') if m > 5 disp('m is greater than 5') elseif m == 5 disp('m is equal to 5') else disp('m is less than 5') end ```
``` Check value of m: m is less than 5 ```

MATLAB contains built-in functions and constants, such as 'abs' (absolute value) and 'pi'.

```disp(' ') disp('Calculate sine of pi/2, and assign it to y:') disp('>> y = sin(pi/2)') y = sin(pi/2) ```
``` Calculate sine of pi/2, and assign it to y: >> y = sin(pi/2) y = 1 ```
