Chapter 267 Libraries

Tsinghua University Library.

Cheng Nuo looked for the books needed to learn matlab programming in the rows of bookshelves.

Zhou Jianxing's "matlab from entry to proficiency", the English version of "The mathematics of derivatives securities with applications in MATLAB", and the specific application of "MATLAB Mathematics Paradigm Course".

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

Cheng Nuo had never dabbled in Matlab programming.

However, this does not affect his high learning efficiency as always.

As long as Cheng Nuo finished reading all three books, it shouldn't be a problem to use Matlab software proficiently.

The first book Cheng Nuo read was "Matlab from Beginner to Master" written by Zhou Jianxing. For those who have zero basic learning of matlab software, 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, etc., are included in this book or More or less involved, it can be said to be very comprehensive.

2.5 cm thick, 284 pages.

Eat it!

Cheng Nuo raised his wrist and checked the time.

One thirty in the afternoon.

There are not many students in the library.

Cheng Nuo flipped through the pages at his own pace.

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

Cheng Nuo was completely immersed in it, absorbing the knowledge contained in the book like a sapling, and did not notice at all that a girl had sat across from him at some point.

After half an hour...

Cheng Nuo closed the last page of the book and let out a soft breath.

As soon as he looked up, he saw the girl with short hair smiling at her across the desk.

Cheng Nuo froze for a moment, "Student, you..."

"Oh, it's okay, I see you are too absorbed in watching, so I don't have the nerve to disturb you." The short-haired girl smiled.

Pointing to Cheng Nuo's position, she said, "Look in the hole of the desk to see if there is 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 table hole for a while. Sure enough, he touched a hard object. He took it out and saw that it was a pink power bank. "It should be this." Cheng Nuo handed it to the short-haired man opposite him. girl.

"That's it, classmate, thank you." The short-haired girl brushed her hair by her ear and thanked her with a smile.

"Should be." Cheng Nuo pushed aside the "Matlab from Beginner to Master" that he had finished reading, and picked up the full English version of "The mathematics of derivatives securities with applications in MATLAB".

This book is much higher than the previous one in terms of difficulty.After all, the previous book was just an introductory textbook, which only briefly explained some knowledge systematically.And this English version of matlab is

"Student, are you from the Department of Mathematics?" The short-haired girl didn't leave after taking back her power bank, but put down her schoolbag directly, placed her laptop in front of her, rested her chin with both hands, blinked, and asked.

"Ah?" Cheng Nuo said, "I guess so."

The short-haired girl had long noticed the books in Cheng Nuo's hands, "So, are you reading these books about MATLAB to prepare for next year's modeling competition?"

Cheng Nuo lowered his head, flipping through the book at a speed of five seconds per page, while distractedly talking to the short-haired girl, "Not really, I'm working on something right now, and I need this software urgently. So I'm learning."

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

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

This is her graduation thesis, the current progress is 20%.

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

Two people sat opposite each other, one gnawed a book and the other rubbed a paper.

In the surrounding area, there was only the sound of flipping books and the clicking of keyboards.

But soon, less than 5 minutes later, a buzzing sound came from her ears, causing the short-haired girl to stop typing on the keyboard and frown slightly.

She tilted her head and looked at Cheng Nuo who was sitting opposite her.

She frowned, not because Cheng Nuo turned the pages too loudly, but...too fast!
Looking at it now, it really is.

One page per second, no, to be precise, one page per 0.8 seconds.That speed doesn't feel like reading a book at all.

"Well, classmate, are you... studying?"

"Yeah, what's the matter!"

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

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

first time?
With your page-turning speed, even if you say it ten times, she won't have the slightest doubt.

She was a little messy in the wind.

"Then you... Okay, you can do whatever you want." The short-haired girl hesitated to speak.

But in her heart, she didn't quite believe Cheng Nuo's words.

This guy... is probably a pretender!

Well, the girl with short hair gave Cheng Nuo a very fair evaluation.

Cheng Nuo also listened to the short-haired girl swallowing half of her words with a puzzled expression.

He smiled helplessly and continued to read the book.

gnawing book ing...

after an hour……

Cheng Nuo simulated in his mind the MATLAB code of the last example given in the book "MATLAB Mathematics Example Tutorial", and smiled with satisfaction.After that, he stacked the three books on the desk together, got up, and prepared to call it a day.

On the other side of the desk, the girl with short hair heard Cheng Nuo's voice, took off her earphones, and looked at Cheng Nuo with confused eyes.

Cheng Nuo greeted politely, "Student, I'm done, so I'll leave first."

It wasn't until Cheng Nuo's back was almost out of her sight that her dazed mind realized, "Oh, wait a minute."

This abrupt voice was not small.

The echo echoed in the huge library, and in an instant, Qi Shushu looked at the short-haired girl.

The short-haired girl blushed, and he grabbed Cheng Nuo who had walked back by the skirt, pushed him onto the stool next to him, lowered his voice, gritted his teeth, and looked down at Cheng Nuo from a height, "Don't Walk."

won't let me go?Your face is still so red?
Could it be that he was attracted by my appearance and wanted to take the opportunity to rape me?

However, doing that kind of thing in a place like the library seems...not very good!
Cheng Nuo was a little excited... Ahh, no!It's a little confusing.

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

"Oh, I know what you want 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 in height, weigh 74 kg, I don't smoke, I don't drink alcohol, and I have no bad habits. Healthy private life, um, and... a good life!"

The short-haired girl's face was so red that it seemed like she could bleed. She stared at Cheng Nuo with a vicious look, "I'm not asking you this!"

"then you?"

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

"Of course, I've been watching it for more than an hour. If I still can't learn it, I'll be sorry for my status as a top student!"

"Then... help me take a look at this."

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

Cheng Nuo looked at the computer screen...
