      So very touching of you to say that. I am humbled by it! Thank you.
      I hope you purchased the book on Amazon. In Kindle it is quite inexpensive.
      Thank you very much again for your kind words – Charan

    I have read enough of your tutorials to know that your book will be excellent but you need to add a link to places that sell it. 🙂
    Thank you for providing Matlab to go with it. For anyone who doesn’t have or can’t afford Matlab, Scilab is an open source alternative that can run all Matlab code. This is a link to it
    Freemat is another Malab clone but I don’t know as much about it (

    Any chance of getting the answers to the book questions?

    Also, will there be an update to the ebook if you’ve already purchased?

    Great book so far…love it.

      Since the book is being used as a text book, I am asked not to provide the answers on the open forum. The questions are actually designed to be pretty simple. Perhaps, I will create a page, where students can post their answers.

      Thanks a bunch for letting me know, you liked the book. I have looked into how to provide update to the Kindle eBook but really can not figure out a way to do that. Amazon does not offer updates of Kindle eBooks. I wish they would let you download the latest version.

      Thanks again,
