The first tennis competition of Tsinghua University came to an end with pingcun's initiative to admit defeat.

What the audience is fond of talking about is that Cheng Nuo, who pretends to be a criminal, comes back to the world after half a year's silence.

Although the forced sports have changed from mental exercise to physical exercise, but Still familiar taste, or the same feeling.

People said that Cheng Nuo is still that Cheng Nuo, that simple and unadorned pretended to be a criminal!

A week later.

A small conference room in Tsinghua University.

The four members of the research group held a brief meeting on the progress of the project. Professor Liao did not attend.

Now, Liao's trip is totally a kind of stocking attitude towards the four people in Cheng Nuo's research group.

As they have been busy with other difficult subjects, Cheng Nuo's project is only an ordinary one, and Professor Liao has no time to take care of it.

It has been three months since the project was studied, but almost all the work was done by the four of them.

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

If only such a difficult project can not be completed, it is better to go home and plant land!

After the four were depressed for a while, they had to rely on themselves as much as possible to solve the problem.

…………

"It's the end of November now, and half a month in February there are exams. Plus review time, so, if we want to stay in school during winter vacation, we'd better finish it in two months

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

"Now, Cheng Nuo, the first part of your project, the construction of a linear system of two-dimensional Helmholtz equation, has been completed. And it took less than half a month to finish. This speed is really beyond my expectation. "

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

"Don't talk about anyone else." Jiang Shuobo glanced at Wang Jian faintly, "you are in charge of the second part, the correction of deficient rank of coefficient matrix. How is it finished?"

"That That. " Wang Ji scratched his head awkwardly, "senior student, as you know, I have been revising my SCI paper some time ago. As for the progress of the project, the deficiency rank correction of the four corner points is now half of that. "

"Only half of it?! You... " Jiang Shuobo slapped the table, so angry that he shouldn't have said anything.

"Boss, boss, don't be angry, don't be angry." Wang Ji shuddered and quickly pacified, "boss, I promise you, within a week, it will be finished."

Jiang Shuobo's expression was not affected, but he was staring at Wang Ji.

Wang Ji's heart was a little flustered.

"Foundation, I heard that your paper has been included in SCI journals. Don't you celebrate it?" Zhuang broke dawn to remind.

"Oh, yes, yes, yes!" Wang Ji patted his thigh and said with a smile to Jiang Shuobo, "schoolmaster, and dawn, Cheng Nuo, let's treat this evening and celebrate. By the way, I'll apologize to you."

Wang Ji glanced at Jiang Shuobo's face and bit his teeth fiercely, "seafood feast!"

"No problem."

"Yes."

"I'm free!"

Hearing the four words "seafood feast", three people's eyes lit up at the same time. Nod your head to show agreement.

Jiang Shuobo patted Wang Jiji on the shoulder and said, "foundation, you are also a member of our team. It's proper to understand each other. Even if this matter has been uncovered. If you have difficulties, you have to face them together. If you have time to catch up, you still have time. "

Wang Ji was a little moved.

Jiang Shuo Bo, pretending to be indifferent, added, "by the way, the treat tonight must not be forgotten. I heard that there is a seafood restaurant near the school, which is very delicious. Otherwise, we can go there. "

Wang Ji: "it's just

"Good ok Schoolmaster, listen to you. "

…………

The dinner was arranged, and Jiang continued to talk about the previous topic.

He pointed to a pile of A4 paper in the hands of several people, and slowly opened his mouth, "during this period of your two research topics, I and dawn are not idle."

"We have almost worked out the detailed steps of the latter three parts of the project. Just wait for the results of the foundation to come out, and then we can start work. "

"But..." Jiang Shuo Bo's words turned, tone with a light worry, "however, we do detailed steps, found a more serious problem."

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

"This is what Jiang Xuechang said." Cheng Nuo, who has been looking down at the A4 paper handed by Jiang Shuo Bo, points to one of the lines and says.

The fifth step is to refine the paper.

That is to say, by which way, the final research results are replaced by numerical experiments.Jiangshuobo nodded, looked at Cheng Nuo, and said slowly, "yes, it is here."

"Based on our previous ideas, this part can be used to replace numerical values by manual calculation or by copying calculations with calculators. But, after careful study, it was not. "

"I wonder how simple it is to think about the algorithm that was finally solved with the preprocessing system. That complexity, coupled with the huge amount of computation, is not calculated manually. "

“so？” Cheno opens.

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

“matlab？”

This name, cheno, has heard of it.

Matlab is a high-level technical computing language and interactive environment mathematical software for algorithm development, data visualization, data analysis and numerical calculation. In the field of mathematics, many data processing and image drawing need to be applied to this software.

However, for college students, it is not yet deep, so it is rarely used.

"Yes." Jiang Shubo nodded, "the situation is that we must use matlab to solve the final step of the project."

"So I want to ask you two, will you use matlab programming?" Jiang Shuobo asked about Cheng and Wang Ji.

The two shook their heads together.

"That's no way. I don't know this knowledge with dawn. " Jiangshuobo shook his head with a bitter smile.

Learning matlab programming, difficulty and time spent, in fact, and learning a C language or Python language is similar.

They don't have time to study software that a university may not use once in four years.

So, it's a bit difficult to do now.

"Well, I can only ask the students over there, if I can," Jiang said

"Jiang Xuechang, in fact, it doesn't have to be so troublesome."

Just as Jiang Shuobo sighed, a voice rang in his ear.

Jiang Shuobo looked at the source of the voice. "Chenuo, what do you mean?"

"Chief, let me come!" Cheno's tone is very firm.

"But you didn't say that?" Jiang Shuobo was in a fog.

He clearly remembers that chenogang just said he can't program matlab.

"No, I can learn!" Cheno smiled with ease. "Give me a day, enough!"

Cheno had meant to give him an hour of time that was all right.

But that would seem crazy.

Then One day!
