  Thanks for the information on MATLAB. There are many here who are interested as there was a previous post about it. Now if its possible for you to write an introductory tutorial on MATLAB then it would be wonderful!
  
  I am giving a presentation on MATLAB this wednesday at my college, and I just might write something at the same time or make a video (extremely less possibility 😀 ).
  
  So, if you or anyone here knows matlab, just write a small intro, better if it comes with pictures, and wow if with vidoes 😀

  Hey dude, like I said the tutorials by MAthworks are the best.
  If you don't have the full version you can see those tutorials online.
  I will post the link :-

  if you have access to original version ,it's well and good!

  Nice post mastermind. Looking forward to more such posts from you.

  😀 So true MM303, even in class when they ask we cannot find good book, then I tell them the help file with MATLAB itself is really good, and even the online tutorials by Mathworks itself, there are a few groups too online which provide total basic training!
  
  Excellent, thanks again.
  
  And I think it would be nice if some can post sample codes or ask for help on this thread.

  I just gave a presentation on MATLAB in my college, it was great, given that I have nevr spoken unofficially, and even that the students never attended a MATLAB presentation before.
  
  Learn it, it can be pretty handy, and MATLAB mathworks website has a lot of stuff anyway.

  Anyone know where I can find good Scilab tutorials? I want to practice MATLAB-stuff at home, so gonna use the free Scilab for that.
  
  xheavenlyx, a video tutorial on MATLAB would be certainly cool! Why not try to do one 😀 I believe theres a thread on how to make screencasts somewhere in CE.

  Thanks for the encouragement dude. I will do that the comming week after my project gets a little cool on the tracks, I havent touched it in a while or else my mentor will hang me. 😁

  Guys, since we all know how valuable MATLAB is, perhaps we can do a simple project with it? Some kind of analysis or something. If we have programming problem solving on CE, why not have a MATLAB one? 😀

  Super. Let us execute a small project on CE 😀

  hi all,
  A project in Matlab... sounds interesting. I do hope it'll be based on image processing.(I'm a bit more acquinted with image processing than other areas of Matlab..)
• 

  Ashraf HZ

  How about image mosaicking using MATLAB? It'll be interesing.. some of us takes a number of shots while turning the camera, and we'll stitch and warp them to make a panoramic image. I think there are some dedicated software out there that do this, but it'll be a good exercise to utilize MATLAB.
  
  A quick and fun project! Then we'll showcase the images 😀

  Here is a small image processing example from MATLAB.
  
  

  %% Block to process RED color. THIS IS A TEST!
  
  RGB = imread('peppers.png'); %Read the image file from any location. This example image will be in your MATLAB folder:
  
  BW = roicolor(RGB(:,:,1),200,255) & roicolor(RGB(:,:,2),0,100) & roicolor(RGB(:,:,3),0,100); %Create a ROI (Region of Interest) in a selected color area. Like Red from 200to255, Green0to100 and Blue0to100 This is the raw basic method, there are many many more ways to find color in an image or in video frames!
  
  subplot(1,2,1), imshow(BW); subplot(1,2,2) , imshow (RGB); %show the original and the ROI based image side by side using 'subplot'.
  

  
  Original on the Right and Selected red color (in white) on the left.
  
  If anyone can run this and explain it better, I would be greatful 😀 Post more examples if you have here.

  Yes, it's very nice for engineers, but it cuts all the fun for programmers 😉

  You're telling me Matlab is not fun at all? 😛
  
  btw, a nice small example, xhx. Hope to see more 😀

  I have used MATLAB with DSP kits and thanks for the information about it.

  anyone here knows about wavelet toolbox in matlab?
• 

  xheavenlyx

  Nope sorry, I have personally never worked with it much. They are used mainly in specific subjects.
• 

  deepmali

  Oh...In case you have any idea about Image Processing using Wavelets,jus tell me
• 

  xheavenlyx

  Wow, now i remember hearing it somewhere. I had a preconceived idea in my head that 'wavelets' are related to "communication" stuff. But its also used for Image Processing as you have reminded me. I will take a look into it.
  
  By then, if you can Google some examples and explanations then please post them here, ok? Try to 😀
  
  Something I found in Google on wavelets in Image Processing:
  
  Here is one lecture by #-Link-Snipped-# on this page: #-Link-Snipped-#

  Hey thanks! Sure i will post things related to Image processing using wavelets here for thats the project I am currently working on.

  Hi here is some material related to wavelets and image processing...

  I'll also try to post things more related to Matlab part of this soon.

  Hi
  
  Could anyone tell me how to store filenames in array and access filenames(to open the file) if they are stored in an array.

  Could anyone tell me how to store filenames in array and access filenames(to open the file) if they are stored in an array.

  Though characters can be stored in arrays in MATLAB, it may be easier to store filenames in cell arrays, especially since cell arrays handle items of varying size more naturally than ordinary 2D arrays. Here's an example:
  

  >> FileNames = cell(4,1);
  >> FileNames{1} = 'COMMAND.COM';
  >> FileNames{3} = 'MODEL.EXE';
  >> FileNames{4} = 'AUTOEXEC.BAT';
  >> FileNames
  
  FileNames =
  
  'COMMAND.COM'
  []
  'MODEL.EXE'
  'AUTOEXEC.BAT'
  
  >> FileNames{1}
  
  ans =
  
  COMMAND.COM
  ​

  Try help cell for more information.

  Who can do a comparison of MATLAB with the free work-alike software called Octave? #-Link-Snipped-#

  Hi all,
  
  Can someone please help me. I need to buy the matlab software in dubai. Does anybody know where is it sold? Or it is available to download in some sites. Are these trustable?
• 

  xheavenlyx

  You can buy it online at: #-Link-Snipped-#
  
  Its safe these days but just make sure you run a through virus scan before the transaction and do it from your home PC. Anyway, which university are you studying in?
