size(A)⇒(3,2)size(A,1)⇒(3)
2.Generating a random matrix
A = randi([1 4],3,5)⇒3 4 4 4 3
4 1 2 2 2

Registered on a Coursera course.
Having an interest on Machine Learning, I registerd one of courses. Luckily I have some time for learning it now not like the previous time I registered on an Udacity’s Machine Learning course paying nearly 500 bucks. The lesson videos are not too long and clear to understand. Started to feel that it’s a good deal to me. Looks like many universities selling their contents on this platform. They started new subscription bussiness.

Learning language by watching dramas.
I like Netflix. It offers many classic dramas and animes with multiple subtitles and audios. Seinfeld and Friends is my favorite. These’re fun and easy to follow. Best learning resource to learn english for me. Besides English, I am also trying to learn German (or have to confess struggling. it’s difficult to pronaunce words correctly) by watching classic dramas. Pastewka and Faust. I bought these dvds. As the subtitle didn’t comes along with, had to find transcript on web and did it after long hours research. This web site is really helpful.

Is WordPress not enough secured for online shop?
Does WordPress get many hacking access? Yes. one of my WP web sites gets sometimes two hundreds of unknown login-attempt access from over the world in a day at most. Whenever unknown login-attemps occur, WP send alert email to the owner’s account. And some of these successfuly loged in as admin user? The answer is no. If one hacker had a his (or her) lucky day, would the one steal your credit number info from WP website? Online payment plugins used in WP like paypayl, stripe(Saas) don’t save that critical infomation on the WP server so hackers can’t get your credit number from WP website.
