## Basic MATLAB command

editDuring start to use the program, you may see "double greater than" symbols aka `>>`

on the top left of command window.

You can start to type simple or complex mathematic equation to your liking.

Some of the examples are as follows:

```
>> 6+3 - 4/2
ans =
7
>> sind(30)
ans =
0.5000
```

or you may even assign a value to a variable / perform simple algebra equations

```
>> x = 200 % assigning value 200 to variable x
x =
200
>> y = 120 % assigning value 120 to variable y
y =
120
>> p = x-y % make a simple subtraction equation where the x is subtract y equals to p
p =
80
```

### Basic Commands

editThese commands listed below are the commands that you usually will encounter when using MATLAB

**clc** - Clear command window.

**clear** - Remove all variable values from workspace

**disp** - Display the values inside of the variable / matrix

**help** - Display tooltip help text inside the Command Window. The **help** displays the help for the functionality specified by NAME, such as a function, operator symbol, method, class, or toolbox.

### Hello World

editOnce Hello World, which is the simplest of programs, works the beginner can move on to explore the MATLAB workspace available for developing or running Matlab code.

Using the workspace the beginner can then learn to manipulate basic MATLAB Variables .

For convenience Matlab allows the workspace to be saved and loaded using *.mat files.
