Matlab basics

(read "matlab what is it used for " first)

the white area in the middle is the work area in which the user types in the commands which are interpreted directly over there and results are displayed on the screen. >> is the matlab prompt indicating that user can type in the commands here...a previously entered command can be reached with the help of up-arrow and down-arrow

In this article the things that u need to type in matlab command window are put in " ". please do open matlab , type them and match the results

it will help u in learning faster.

Simple commands:

Type this is the work area and press enter

>>" 3ˆ2 - (5 + 4)/2 + 6*3"
this will result in
ans =
22.5000


matlab defines a new variable "ans" as ur result and u can use it again newhere
chk these examples these will make u understand every basic command u need to know in matlab



Example 1:

To perform symbolic computations, you must use syms to declare the variables
you plan to use to be symbolic variables.


>>" syms x y"
>> "(x - y)*(x - y)ˆ2"
this will result in
ans =
(x-y)^3

>>" expand(ans)"
this will result in
ans =
x^3-3*x^2*y+3*x*y^2-y^3

>>" factor(ans)"
this will result in
ans =
(x-y)^3

MATLAB- what is it used for?

To get u inspired...let's see what all it can do

1. Matlab is a software used for analysis of systems that can be modeled as matrices. These include digital filters, signals, communication channels, mechanical systems etc. This has widely been used to perform simulations and analysis of signal processing, neural networks and control systems algorithms by researchers. Matlab is probably the single most important software you are expected to be familiar with as an electronics engg student, followed by Spice and VHDL.
   
2. Complex calculus solves for example, Linear System, Polinomy, Matrix, Diferential Equation, Diferential Equation Systems, etc.
3. Make GUIs (graphical user interface)
   

There are many toolboxes in it and the two m interested in particular are:

1.Image Processing Toolbox™ software provides a comprehensive set of reference-standard algorithms and graphical tools for image processing, analysis, visualization, and algorithm development. You can restore noisy or degraded images, enhance images for improved intelligibility, extract features, analyze shapes and textures, and register two images.

apps i got thru last few months

DEEPZOOM :

can be used in web pages ,nice application in which u can zoom by clicking 

that too very fast and embed images in web pages yoyoyo

FACESHOP:

nice way to create faces to be used in 3d softwares

PHOTOSYNTHS:

 really cool nd revolutionary.....a software to create a 3d environment out of 

2d pics and to include it on our webpage really very nice.....photosynths.net

VIRTUAL PC:

another operating system in the old operating system

ANDREA MOSIAC :

software to create photomosaic gives a image very large 

upto 100mb and zoom to a very gud level where u can see all ur photos in the mosiac works awesome when used with deep zoom

EXPRESSION BLEND :

to insert video audio and aimation soon silverlight 3 

coming in which we can add 3d animation and make animation on the web pages which uses silverlight...very powerful ne thing can be done!!!!!!!!!!!!!!!!!!

BRUSHES FOR PHOTOSHOP: 

everytype of brushes available just have to use the creativity...very cool ready make copyright free applications..paste in the directory of brushes

POWERPOINT-nice reflection...in formatting can be very useful for web desgining chk the background it is edited with powerpoint and also it changes the size of images to few kbs...same pixels as apper in powerpoint so very good for reducing size and pixels  nd wordart also very nice

EXPRESSION MEDIA ENCODER....for live broadcasting in the website and encodes pre recorded video's

MAMBO - free database site creator just install in website

JOMLA - the best fukin awesome create your dreamsite in seconds 100+ templates available
