2015-10-14 It is difficult to write the explains of software tool easy-to-understand. [長年日記]

We can get some book for "MS word and excel" just for 500 yen.

Unfortunately, I am afraid that the quality of the books seems not to be good.

Difficult, small characters and all kinds of function that will not be used --- in short, they are illegible books.

But it cannot be helped. Publishing companies don't pay much money for the 500 yen books.

And the "500 yen" is attractive for me.

Last week, I went to Kanda's book street to find MATLAB and Simulink of the 500 yen book, and it was in vain. Moreover I could not find a book for beginners.

Come to think of it, there is no market, indeed.

Absolutely, the market size is determined by the number of research engineer who in special have a high-mathematical mind, need statistical work and hope to make sequenced and discrete event simulation technologies.

Above all, the prices of the software are more than 800k~2000k yen.

(If I were a student, I could get them at about 10k yen, and absolutely would buy it.)

It is difficult to write the explains of software tool easy-to-understand.

The most important point is not "how to add the function" but "how to delete the function". It depends on editor's philosophy.

If all functions are described, the readers are difficult to complain about the book.

But after all, I think "describing all" is the same of "describing nothing".

To tell you the truth, "writing long is disgusting!"

Suddenly, I decided to stop today's diary now.

I have just noticed that "it is me that who ties myself down"
