The first tennis tournament of Tsinghua University officially came to an end with the initiative of Pingcun Tree Planting to admit defeat.

What the audience is talking about is naturally that Cheng Nuo, who pretended to be a criminal, reappeared after being silent for half a year.

Although the project of pretending to be forced has changed from mental exercise to physical exercise, it ...... It's still a familiar taste, and it's still the same feeling.

Everyone said that Cheng Nuo is still the same Cheng Nuo, the simple and unpretentious pretending criminal!

A week later.

A small conference room at Tsinghua University.

The four members of the research group had a brief meeting on the process of the project, which Professor Liao did not attend.

Now, Liao Zhixing has a completely free-range attitude towards the four people in Cheng Nuo's research group.

Since he has been busy with other difficult topics, Cheng Nuo and their projects are only ordinary level, and Professor Liao has no time to take care of them.

Three full months have passed since the research time, but almost all the work is done by the four of them.

Anyway, in Professor Liao's words, this project is for them to practice.

If you can't complete a project of this difficulty, then you might as well go home and farm!

After the four of them were depressed for a while, they could only rely on themselves as much as possible to solve this problem.

............

"It's the end of November, and half of February has exams. In addition, there is time for revision, so if we want to stay in school during the winter break, we had better finish it within two months. ”

Jiang Shuobo took out a printed stack of A4 paper and distributed it to the other three people present.

"The current situation is that the first part of the project that you are responsible for, that is, the construction of the linear system of the two-dimensional Helmholtz equation, has been completed. And it took less than half a month to get it done. This speed was indeed beyond my expectations. ”

"At the beginning, I was also surprised by Cheng Nuo's speed. Wang Genji spoke on the side.

"Don't talk about anyone else. Jiang Shuobo glanced at Wang Genji lightly, "You are in charge of the second part, the correction of the coefficient matrix, how is it done?"

"That...... That one. Wang Genji scratched his head a little embarrassed, "Senior, as you know, I have been revising my SCI paper some time ago. As for the progress of the project, the deficit correction at the four corners is now halfway through. ”

"It's only half?!...... you "Jiang Shuobo slammed the table, so angry that he shouldn't have said anything.

"Boss, boss, don't be angry, don't be angry. Wang Jiji trembled with fright, and hurriedly reassured, "Boss, I promise you, within a week, it will definitely be done." ”

Jiang Shuobo's expression was unmoved, just staring straight at Wang Jiji.

Wang Genji's heart was a little panicked.

"Foundation, I heard that your paper was included in the SCI journal, don't you celebrate?" Zhuang Poxiao reminded him.

"Oh, yes, yes!" Wang Genji slapped his thigh and said to Jiang Shuobo with a smile, "Senior, and Dawn, Senior Brother Cheng Nuo, then we will have a treat tonight and celebrate, and by the way, I will apologize to you." ”

Wang Genji glanced at Jiang Shuobo's face and gritted his teeth fiercely, "Seafood feast!"

"No problem. ”

"Yes. ”

"I'm free!"

Hearing the words "seafood feast", the eyes of the three of them lit up at the same time. Nod in agreement.

Jiang Shuobo patted Wang Genji on the shoulder, "Genji, you are also a member of our team, mutual understanding is due, even if this matter is revealed." If there are difficulties, we must face them together, and we will catch up with the time, but it is still too late. ”

Wang Genji was a little moved.

Jiang Shuobo pretended not to care and added lightly, "By the way, tonight's treat, you must not forget it." I've heard that there's a seafood restaurant near the school, and it's very delicious, so let's go there. ”

Wang Genji: "......"

"Good...... All right. Senior, listen to you. ”

............

The matter of inviting guests to dinner was agreed, and Jiang Shuobo continued to talk about the previous topic.

He pointed to a stack of A4 papers in the hands of several people, and said slowly, "During the time when the two of you were researching the topic, I and Dawn were not idle. ”

"In the last three parts of the project, we have almost figured out the specific details of the steps. Just wait for the results of the foundation to come out, and then you can start work. ”

"But......" Jiang Shuobo's words changed, and his tone was tinged with apprehension, "However, when we did the refinement steps, we found a more serious problem. ”

"What's the problem?" asked Wang Genji.

"What Senior Jiang said, it should be this. Cheng Nuo, who had been looking down at the A4 paper handed to him by Jiang Shuobo, pointed to one of the lines of text and said.

That's a detailed step in the fifth part of the paper.

That is, by what means, the final research results are substituted into numerical experiments.

Jiang Shuobo nodded, glanced at Cheng Nuo, and slowly spoke, "Yes, this is it." ”

"According to our previous idea, this part can be calculated manually or by copying the calculation with a calculator to carry out the experiment of numerical substitution. However, upon closer inspection, it turns out that this is not the case. ”

"It's also my fault that the algorithm that was finally solved by the preprocessing system was too simple. That level of complexity, combined with the sheer amount of computation, is simply something we can calculate manually. ”

"So?" Cheng Nuo said.

"So, we can only use MATLAB to do the numerical substitution experiment in the fifth step!"

“matlab？”

Cheng Nuo had heard of this name.

MATLAB is a high-level technical computing language and interactive environmental mathematics software for algorithm development, data visualization, data analysis, and numerical computation. In the field of mathematics, a lot of data processing and image drawing need to use this software.

However, for college students, the depths are not yet there, so this software is rarely used.

"Yes. Jiang Shuobo nodded, "The current situation is that we have to use MATLAB to complete the last step of the project." ”

"So I want to ask the two of you, do you know how to program in MATLAB?" Jiang Shuobo naturally asked Cheng Nuo and Wang Genji.

The two shook their heads in unison.

"That can't be helped. Dawn and I don't know anything about this. Jiang Shuobo shook his head with a wry smile.

Learning MATLAB programming is about the same as learning a C or Python language in terms of difficulty and time.

They don't have the time to dedicate themselves to learning software that they might not even use once in four years at university.

So, the situation is a bit difficult to deal with now.

Jiang Shuobo opened his mouth and said, "Alas, it seems that I can only ask the classmates on the other side of the Accounting Institute if they have any skills." ”

"Senior Jiang, in fact, you don't have to be so troublesome. ”

Just as Jiang Shuobo sighed, a voice sounded in his ears.

Jiang Shuobo looked at the source of the voice, "Cheng Nuo, what do you mean?"

"Senior, let me come!" Cheng Nuo's tone was very determined.

"But didn't you just say?" Jiang Shuobo was confused.

He clearly remembered that Cheng Nuo just said that he didn't know MATLAB programming.

"No, you can learn!" Cheng Nuo smiled easily. "Give me a week, that's enough!"

Cheng Nuo originally wanted to say that it would be completely fine to give him a day.

But that would be crazy.

Then ...... Let's do it for a week!
