Essential MATLAB and Octave – Closer to publication date

The publication date of “Essential MATLAB and Octave” is getting closer and closer. I would like to use this as an opportunity to share yet another endorsement, this time from Dr Hiram Luna-Munguia from the Department of Neurology at the University of Michigan:

This well-written book is a must-have for those people starting to solve numerical problems in Matlab or Octave. Since the beginning the reader will appreciate that the book´s major goal is to describe the essential aspects of both software without discrediting or highlighting the use of any of them. Page by page you will find clear explanations describing the way you should communicate with each software. The set of homework problems given at the end of each chapter makes the book even more dynamic.

Students and experts will warmly welcome Essential Matlab and Octave: A Beginner’s Handbook into their libraries. I highly recommend it as an excellent reference tool.

Essential Matlab and Octave – Publication Date

I have received very good news from CRC Press in regards to the publication of my book “Essential Matlab and Octave”: The publication date for the book in the US is November 13th, and the UK following after one or two week.

Also, the endorsements for the book are very good and I thought of sharing one from Dr Shashank Virmani from the Brunel University, UK:

“Essential Matlab and Octave” is a superb introductory textbook for those interested in learning how to solve scientific, engineering, and mathematical problems using two of the most popular mathematical programming tools available — Matlab and Octave.

The book assumes almost no prior experience with programming or scientific programming, and carefully takes the reader step-by-step through the use the of the two languages for solving increasingly complex problems. It begins with elementary tasks such as the evaluation of simple functions, takes the reader through the basics of plotting figures and programming syntax, leading up to a chapter of more sophisticated examples of problems to suit a diverse range of tastes, including linear algebra applications, the solution of differential equations in physics and biology, signal processing, and problems in mathematical finance.

Dr. Rogel-Salazar has put a huge amount of effort into making the book accessibly and user-friendly in a way that makes it suitable even for the most novice of programmers. The layout of the book is used very effectively with boxes that give clear and concise example programmes and the use of side notes to point out where differences can occur between Matlab and Octave, and to provide references and additional information.

Just the right balance of content is chosen for a beginner to quickly reach a stage where they can begin to write useful programmes of their own. Enough detail is included to point out the power and major stumbling blocks, without overburdening the reader with too much detail on the more subtle aspects that they can only come to appreciate after further experience of programming. This helps the textbook fill a useful gap in the market, and make it an excellent companion to introductory courses on scientific computation in degree programmes, as well as an accessible but concise guide to anyone learning how to use such tools by themselves”


Essential Matlab and Octave – Endorsement

With the up-coming publishing of my book Essential Matlab and Octave, it is great to star receiving endorsements from practitioners and lecturers that have had a chance to review the book. Here I have the pleasure of sharing one:

Essential Matlab Octave Rogel-Salazar


From: Dr Alan McCall, University of Hertfordshire.

The text provides a clear and easy paced introduction to Matlab and Octave. The presentation is example led and contains plenty of useful applications drawn from mathematics, physics and engineering. This beginner’s handbook will suit a broad scientific readership.

Key features:

  • The in-parallel coverage of Matlab and Octave.
  • All key software features are covered in a concise and careful manner.
  • Includes many of the common scientific computing tasks for which the software can be used.
  • Contains a wide range of applications from linear algebra, portfolio analysis, differential equations, signal processing, wave motion and quantum mechanics.
  • Provides lots of useful practical tips not found in other texts.
  • The numerous in text examples and end of chapter exercises encourage learning by doing.
  • A suitable text for a short course or a useful reference for self-study.

Matlab and Octave book: Update

I am super excited as I have just received what seem to be the final corrections from the CRC Press copyeditors in regards to my book “Essential MATLAB and Octave”. The total corrections amounts to one (1) comma! Not bad!

You can have a look at the CRC Press for the book here.

In Amazon, you can find the book here.

Update on Essential Matlab and Octave

I am very pleased to announce that I have submitted the final version of my book entitled “Essential MATLAB and Octave” to CRC Press. Also I have seen a preliminary cover, and they indeed have used the figure I proposed.

Not only that, but it seems that Amazon is already using that image!

MATLAB for mac in Mountain Lion without X11

Well, I have now made the move to Mountain Lion and for a bit it did look quite good, until I had the nerve of trying to start MATLAB. Now, I must admit that the version of MATLAB that I have is by no means the latest, but it does do the work (for those of you who asked, I am running 2008a). So, I realised that the final blow for X11 was given and that Mountain Lion did indeed get rid of it.

I had encountered this issue when upgrading GIMP, and at the time, everything seemed to be working fine with XQuartz. So, there was I thinking to myself “It is just a matter then of re-installing XQuartz and off we go”. How wrong was I! I installed XQuartz, downloaded from here. The first glimpse that things were not quite correct was when I had to tell manually to GIMP the location of X11. Then tried to launch MATLAB and quite quickly the following message popped up:

“X11 does not appear to be installed. X11 version 1.1.3 or greater is required. For OS X 10.5 or later, X11 is available on the OS X installation DVD. Please find and run the Optional Installs.mpkg installer.”

Great thing that Mathworks has told me that, but Apple does not do X11 anymore, so no installing from the DVD, righ?t! Worse still, unlike GIMP, there was no prompt from MATLAB to tell it the location of X11. I tried creating some symbolic links, but this did not work either. Finally, after a lot of fiddling and searching and all, I found a way to run MATLAB successfully. A solution? Oh well here it is:

  1. Install XQuartz
  2. Launch XQuartz and from the menu launch an xterm.
  3. Type the following command first:
  • $MATLAB/bin/matlab -maci

Where $MATLAB is the path to your installation. And voilà!

Incidentally, if you are having problems with the graphics in MATLAB, such as the application crashing when plotting and the like, you can type the following command before launching MATLAB as specified above:

export DYLD_LIBRARY_PATH=/System/Library/Frameworks/JavaVM.framework/Libraries

Let me know how you get on with this and should you find another alternative solution let me know!
