Basics of MATLAB
Define :
MATLAB is stands for matrix laboratory | high level language
it is software package for numerical computation and visualisation
it has hundreds of built in functions. we can plot 2D|3D graphs
Basic building block of MATLAB
Matrix has tools when you understand about tools then you know the things to do so i will show you
File menu: we use to open ,close |save the files like a microsoft view menu: means viewing
Edit menu: as usual we use to edit by using edit menu
Debug menu :to find or by tracing errors in simulation modelling or mathematical modelling
Parallel menu:if we want to run 2 simulation files at a time use this.
we are new but have to do operations how? what is operation ?operation is nothing but addition, subtraction, multiplication |division.
then
 |
| MATLAB |
this is very important feature in Matlab if we want to do operations by using "Help" command we can see this on toolbar.
for example : addition
>> a=10
a =
10
>> b =2
b =
2
>>a+b
ans =
12
>> c =ans so the c is the answer value
so ans means answer,
c is the answer value
we have given any value it stores in matrix form that will show while we are working in MATLAB Software.
if we want to clear the c means just use ">>clc" command
that is why it is very flexible software.
similarly do
??? Undefined function or variable 'a'
>> a=8
similarly do
??? Undefined function or variable 'a'
>> a=8
a =
8
>> b = 9
b =
9
>> c=a+b (Addition)
c=
17
>>d= a-b (Subtraction)
d =
-1
>> e = c*d (Multiplication)
e =
17
>> fx =
now the quitting session rite so quit how to quit not direct we are the engineers we use to follow some rules otherwise will loose data so , just follow to use quit command for quitting
