Mentor of Coursera machine learnig course solved my problem. His comment is as below.

It sounds like your Octave installation was not successful.

Be sure you downloaded the correct word size (32 or 64 bits) for your operating system, and also you should download the Windows executable installer.

For a different reason, you'll do better with version 4.4.1, because 5.1.0 has a defect in one of the functions. The defect makes the exercises difficult to use.

So I installed version 4.4.1, and everything is fine!
