Chapter 267 (1/2)

Tsinghua University Library.

Cheng Nuo is looking for books to learn matlab programming in the bookshelves.

Zhou Jianxing's ”matlab from introduction to Mastery”, English version of ”mathematics of derived security with applications in MATLAB”, and ”matlab mathematics example course” in specific application.

Cheng Nuo took the three books, found a table by the window in the library, and looked through them one by one.

About matlab programming, Cheng Nuo has never been involved.

However, this does not affect his efficiency as always.

Complete the application of MATLAB software, as long as you are not proficient.

The first book Cheng Nuo read is ”matlab from introduction to Mastery” written by Zhou Jianxing. For people who study MATLAB software with zero basis, this book is the best choice.

Matrix calculation, numerical calculation, symbolic calculation, data visualization, data analysis, M-file writing, Simulink simulation, handle graphics, graphical user interface, file reading and writing, matlab compiler, application program interface and other contents are more or less involved in this book, which can be said to be very comprehensive.

2.5 cm thick, 284 pages.

Eat it!

Cheng Nuo raises his wrist and looks at the time.

It's one thirty in the afternoon.

There are not many students in the library.

Cheng Nuo in accordance with their own speed, page by page.

Various array creation, string creation, Cholesky decomposition, continue, break, return, input, keyboard commands.

Cheng Nuo's mind is completely immersed in it, like a sapling, constantly absorbing the knowledge contained in the book. He has not noticed that a girl has been sitting opposite him.

Half an hour later

Cheng Nuo closes the last page of the book and takes a breath.

As soon as I look up, I see the girl with short hair who is smiling at her desk.

Cheng Nuo was stunned, ”classmate, you...”

”Oh, it's OK. It's too much to disturb you.” The girl with short hair smiles.

She pointed to Cheng Nuo's position and said, ”look at the hole in the desk and see if there is a power bank. I studied at your position this morning and forgot to take the power bank away. ”

Cheng Nuo lowered his head and groped in the table hole for a while. Sure enough, he found a hard object. He took it out and found it was a pink power bank. ”This should be it.” Cheng Nuo hands it to the girl with short hair opposite.

”That's it, classmate. Thank you.” The girl with short hair raised her hair and said thanks with a smile.

”It should be.” Cheng Nuo pushed aside the finished ”matlab from introduction to Mastery” and picked up the English version of the ”mathematics of derived securities with applications in MATLAB”.

This book, in terms of difficulty, is much higher than the previous one. After all, the previous book is just an introductory textbook, which only gives a rough description of some knowledge systems. The English version of MATLAB is

”classmate, are you from the Department of mathematics The girl with short hair didn't leave after taking back her power bank. Instead, she put down her schoolbag, set her laptop in front of her, held her chin in her hands, blinked, and asked.

”Ah?” Cheng Nuo said, ”it should be considered.”

The girl with short hair has long noticed the books in Cheng Nuo's hands, ”so, you read these books about MATLAB, in order to prepare for the modeling contest next year?”

Cheng Nuo lowered his head and turned the book at the speed of five seconds and a page, while distracted from talking to the girl with short hair, ”not really. At present, I'm doing something. I need to use this software urgently. So I'm learning. ”

”Oh.” The girl with short hair nodded and stopped talking.

She turned on her computer and went on with her paper work.

This is her graduation thesis, which is now 20%.

However, her graduation defense will be at the beginning of June next year, and there will be plenty of time, so there is no need to worry.

Two people, sit opposite each other, one gnaws a book, one rubs a paper.

Around, only the clattering of books and clattering of the keyboard.

But soon, less than five minutes later, the squeak in her ears made the short haired girl stop her keyboard finger and frown.
