Omnipotent Data

Cheng Nuo stared at the computer screen for a while, then frowned slightly.

He turned his head and looked at the short girl beside him, "Student, what is your major?"

The short girl teased her hair on her temples, smiled slightly, showing a whole row of white teeth, "Let me introduce myself, my name is Jian Yuluo, majoring in civil engineering."

civil Engineering? !

Cheng Nuo's mouth twitched violently.

Girl, you are messing around!

Originally, among the people Cheng Nuo knew, Ying Yingying, who learned electric welding, already made Cheng Nuo feel incredible.

But the one in front of me is good, he is studying civil engineering, this...

civil Engineering!

From the name, this major seems to be quite awesome. But in fact... More than half of the students who come out of this major will go to the construction site. Even college students who graduated from Tsinghua University will not have the slightest exception.

A young girl stays in a dusty construction site every day. No matter how you think about that scene, it makes people feel sorry.

Seeing that Yu Luo seemed to know what Cheng Nuo was thinking, he explained with a smile, "Actually, our major doesn't mean that there is no way out other than going to the construction site."

"I'm currently doing an internship in a design institute in Kyoto, and I'm doing pretty well. If nothing else happens, I should be admitted directly after graduation."

Hearing this, Cheng Nuo couldn't help but glance at Yu Luo.

As far as he knows, most design institutes recruit graduate students majoring in civil engineering. As for undergraduates who can go to design institutes for internships, and hearing Yuluo's tone, it is almost a sure thing that they will be retained. Such students, Definitely a very few of the very few.

And the job in the design institute is to sit in the office and do some simple design and other things. Compared with going to the construction site to be exposed to the wind and the sun, it is simply not too comfortable.

Tsinghua University is indeed a hidden dragon and crouching tiger!

Cheng Nuo once again had a deep understanding of this sentence.

Unexpectedly, the female classmate she met casually was a boss who would work in the design institute in the future.

"So, the one you showed me should be your graduation thesis, right?" Cheng Nuo pointed at the computer screen and said.

Seeing Yu Luo nodding slightly, "Yes, half-finished products are not even considered graduation thesis."

She lowered her head, manipulated the mouse, and brought up one of the dozens of pages of papers. She smiled at Cheng Nuo, "Student Cheng Nuo, I think you have been watching matb programming just now, right?"

Cheng Nuo nodded.

"You also said just now that you already know how to use it completely?" Jian Yuluo said with a smile.

"That's right. Two hours, learning matb software is enough for me." Cheng Nuo pretended to be aggressive.

"..." Seeing Yu Luo expressing that she was not quite used to Cheng Nuo's pretending from time to time, she looked at Cheng Nuo and said loudly, "So, Cheng Nuo, it's time to test your academic achievements!"

Jian Yu Luo directly pushed the laptop in front of Cheng Nuo this time.

"You should be able to use matb to program the algorithm for this problem?"

Seeing Yu Luo looking at Cheng Nuo with uncertain eyes.

Even with a questioning tone?

Cheng Nuo felt that his self-esteem as a top student had been insulted.

Cheng Nuo didn't look at the questions directly, and smiled confidently, "No problem."

After speaking, Cheng Nuo turned his eyes to the computer screen.

Seeing the topic of Yu Luo's graduation thesis, Cheng Nuo glanced at it before, and roughly guessed it.

If Cheng Nuo guessed right, it should be about the design and analysis of structures in civil engineering.

And the page that Yu Luo asked Cheng Nuo to read contained a not-so-small branch of design analysis.

It is "the problem of solving the internal force and displacement of the structure when the structure is under the action of static force and dynamic load".

Through the analysis of mathematical equations, the programming of matb algorithm is carried out, and then the solution is solved.

This is a very complicated process.

The knowledge of mathematics involved in it is enough to make Jian Yuluo, a student majoring in civil engineering, despair.

Originally, according to Jian Yuluo's plan,

I was planning to go to the School of Mathematics to seek help from a student who had participated in a modeling competition.

However, since I met Cheng Nuo today. Of course, no matter whether it succeeds or not, there is no loss in letting him try.

Just in time, Jian Yu Luo wanted to test whether Cheng Nuo had really gone from zero foundation to matb proficiency in less than two hours.

"How is it? Is it difficult?" Half a minute later, seeing Cheng Nuo's realization moving away from the computer screen, Jian Yuluo couldn't help asking worriedly when he saw his slightly gloomy face.

Cheng Nuo nodded, "Indeed, it's a bit difficult."

Cheng Nuo was telling the truth.

Seeing Yuluo is probably because she really doesn't know how complicated the mathematical calculation of "structural internal force and displacement under static and dynamic loads" is, so she fearlessly included it in her graduation thesis.

From the perspective of Cheng Nuo, who is barely a professional in mathematics, in order to be completely accurate with this data, it is necessary to construct a rather complicated calculation equation.

Then, the operation equation must be converted into matb code.

"This one of yours needs to deal with the solution and convergence of the nonlinear equations in the finite element program, as well as the coordinate determination problem of the two-dimensional primary four-node unit." Cheng Nuo explained, "If you use the sub-function method to solve the problem If so, then..."

Cheng Nuo talked a lot, and Jian Yu Luo, who was on the side, was stunned.

What did he say?

Why is it a completely strange feeling when it is clearly my thesis?

Although I don't understand, but it feels troublesome?

Seeing that Yu Luo was in a daze, she asked in a weak tone, "So, can't you?"

"Okay!" Cheng Nuo nodded heavily. He patted his chest and said with a smile, "Although it's troublesome, it's still achievable for me as a top student."

"Then... how long will it take?"

"One... oh no, half an hour is enough!"

an hour is too long,

For Cheng Nuo, who only seizes the day and night, half an hour is considered a long time.

"By the way, do you have matb installed on your computer?"

"Yes, uh, here it is."

"Okay, then I'll get to work."

"Then I..."

"Anything you want. Just come and pick up the program in half an hour."

After speaking, Cheng Nuo lowered his head and took out a stack of draft paper from his schoolbag.

First, establish the algorithm equation.

f=ax^e^n...

…………

It took Cheng Nuo more than ten minutes to go through more than a dozen equations to come up with the algorithm equations required for matb programming.

Then, open matb and enter the code.

Cheng Nuo tapped the keyboard with both hands, as if the code was written in his mind.
