Tsinghua University Library.

Cheng Nuo searched for the books he needed to learn MATLAB programming in the rows of bookshelves.

Zhou Jianxing's version of "matlab from beginner to proficient", the English version of "The mathematics of derivatives securities ith applications in MATLAB", and the specific application of "MATLAB Mathematics Example Tutorial".

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

Regarding MATLAB programming, Cheng Nuo has never dabbled in it.

However, this does not affect his usual high learning efficiency.

As long as Cheng Nuo finishes all the three books, it should not be a problem to be proficient in using MATLAB software.

The first book Cheng Nuo read was "MATLAB from Beginner to Mastery" written by Zhou Jianxing, which is the best choice for people who learn MATLAB software from scratch.

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 programming interface, etc., are more or less covered in this book, which can be said to be very comprehensive.

2.5 cm thickness, 284 pages.

Nibble on it!

Cheng Nuo raised his wrist and looked at the time.

1:30 p.m.

There aren't many students in the library.

Cheng Nuo turned the pages one by one at his own pace.

Creation of various arrays, creation of strings, Cholesky decomposition, continue, break, return, input, keyboard commands.

Cheng Nuo's mind was completely immersed in it, like a sapling constantly absorbing the knowledge contained in the book, without noticing at all that a girl had sat opposite him at some point.

Half an hour later......

Cheng Nuo closed the last page of the book and exhaled lightly.

As soon as I looked up, I saw the short-haired girl on the other side of the desk who was smiling and looking at her.

Cheng Nuo was stunned for a moment, "Classmate, you ......"

"Oh, it's okay, I'm too engrossed to bother you. The short-haired girl smiled.

She pointed to Cheng Nuo's position and said, "Look at the desk hole in the desk, is there a power bank." I was studying at your place this morning and forgot to take the power bank away. ”

Cheng Nuo lowered his head and groped in the hole of the table for a while, and sure enough, he touched a hard object, and took it out to see that it was a pink power bank, "It should be this." Cheng Nuo handed it to the short-haired girl opposite.

"That's it, classmate, thank you. The short-haired girl stroked the hair around her ears and smiled and thanked her.

"It should. Cheng Nuo pushed aside the finished book "MATLAB from Beginner to Mastery" and picked up the all-English version of "The mathematics of derivatives securities ith 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, just a rough introduction to some knowledge systems. And this English version of MATLAB is:

"Classmate, you're from the math department, right?" The short-haired girl didn't leave after taking back her power bank, but directly put down her schoolbag, put her laptop in front of her, supported her chin with both hands, blinked, and asked.

"Huh?" Cheng Nuo said, "It should be counted." ”

The short-haired girl had already noticed the books in Cheng Nuo's hand, "So, you read these books about matlab to prepare for next year's modeling competition?"

Cheng Nuo lowered his head, turning the book at a speed of five seconds per page, while talking to the short-haired girl distractedly, "No, I'm currently working on something, and I urgently need to use this software." So I'm learning. ”

"Oh. The short-haired girl nodded and stopped talking.

She turned on her computer and continued working on her dissertation.

This is her dissertation, which is currently 20% progress.

However, her graduation defense is in early June next year, and there is still a lot of time, so there is no need to be in a hurry.

Two people, sitting opposite each other, one gnawing on a book, the other rubbing a paper.

Around, there is only the sound of flipping books and crackling keyboard tapping.

But soon, less than five minutes, the sound of the buzz in her ears made the short-haired girl stop tapping her fingers on the keyboard and frown slightly.

She tilted her head and looked at Cheng Nuo, who was sitting across from her.

She frowned, not because Cheng Nuo turned the page too loudly, but because she ...... Too fast!

Now that I look at it, it turns out to be so.

One page per second, no, 0.8 seconds per page to be exact. At that speed, it doesn't feel like reading a book at all.

"That, classmate, what are you...... Studying?"

"yes, what's wrong!"

"How many times have you read this book?" the short-haired girl pointed to the all-English book that Cheng Nuo was still flipping through.

"This is just the first time. Cheng Nuo said.

First time?

With your speed of flipping through the book, even if it is said for the tenth time, she will not have the slightest doubt.

She's a little messy in the wind.

"What about you...... Well, you feel free. The short-haired girl stopped talking.

It's just that in her heart, she doesn't quite believe Cheng Nuo's words.

This guy ...... Probably a pretending criminal!

Well, the short-haired girl gave Cheng Nuo a very pertinent evaluation.

Cheng Nuo also listened inexplicably as the short-haired girl swallowed half of her words.

He smiled helplessly and continued to nibble on the book.

Gnawing on the ......

An hour later......

Cheng Nuo simulated the MATLAB coding of the last example given in the book "MATLAB Mathematics Example Tutorial" in his mind, and smiled with satisfaction. Then, stacking the three books on the desk, got up, and prepared to call it a day.

On the other side of the desk, after the short-haired girl heard Cheng Nuo's voice, she took off her headphones and looked at Cheng Nuo with a confused gaze.

Cheng Nuo greeted politely, "Classmate, I'm done, I'll leave first." ”

It wasn't until Cheng Nuo's back was about to walk out of her sight that her confused brain reacted, "Alas, you wait a minute." ”

This abrupt sound is not small.

Echoing in the huge library, in an instant, Qi Shushu's eyes looked at the short-haired girl.

The short-haired girl's face turned red, he grabbed the placket of Cheng Nuo, who had walked back in front of him, pressed him to the stool next to him, lowered his voice, grinded his teeth, and looked down at Cheng Nuo from a high place, "Don't go yet." ”

Don't let me go?

Could it be that you are attracted by my appearance and want to take the opportunity to strengthen me?

However, it seems that a place like a library does that kind of thing...... Not so good!

Cheng Nuo was a little excited in his heart...... Ahh

"You ......" The short-haired girl was still a little confused.

"Oh, I know what you're trying to ask. Cheng Nuo said that he could see through the thoughts of short-haired girls at a glance, "Let me introduce myself, my name is Cheng Nuo, I am 181 tall, weigh 74 kilograms, do not smoke, do not drink, have no bad habits, have a healthy private life, well, and ...... It's a great job!"

The short-haired girl's face was red as if she could drip blood, and she stared at Cheng Nuo with a vicious gaze, "I didn't ask you this!"

"What about you?"

"I just want to ask, have you learned MATLAB programming?"

"Of course, I've been watching it for more than an hour, and if I can't learn it, then I'm sorry for my identity as a scholar!"

"So...... You can help me look at this. ”

The short-haired girl turned the computer and turned the screen to Cheng Nuo.

Cheng Nuo looked at the computer screen......
