Omnipotent Data

The first tennis tournament of Tsinghua University officially came to an end with Pingcun’s initiative to surrender trees.

What the audience talked about was naturally pretending that Cheng Nuo re-emerged after half a year of silence.

Although the pretending item was changed from mental exercise to physical exercise,... it was still a familiar taste and the same feeling.

Everyone said that Cheng Nuo was still that Cheng Nuo, that simple and unpretentious pretending to be a criminal!

A week later.

A small conference room in Tsinghua University.

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

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

Since Cheng Nuo and others have been busy with other difficult subjects, this is only an ordinary level subject, and Professor Liao has no time to take care of it.

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

Anyway, in the words of Professor Liao, this project is for them to practice their hands.

If you can't complete a project of this difficulty, it's better to go home and farm!

After the four were depressed, they could only rely on themselves as much as possible to solve the subject.

…………

"It's the end of November, and the exams are required for the first half of February. In addition, time for review, so if you want to stay out of school during the winter vacation, we'd 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 subject that Cheng Nuo is responsible for, that is, the construction of the linear system of the two-dimensional he1mho1tz equation, has been completed. And it took less than half a month to complete. This The degree is indeed beyond my expectations."

"At the beginning I was surprised by Cheng Nuo's degree." Wang Genji said to the side.

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

"That... that." Wang Genji scratched his head quite awkwardly, "Senior, you know, I have been revising my sci paper some time ago. As for the progress of the subject, the four corners have been corrected by the deficient rank. Now Halfway through."

"Only half?! You..." Jiang Shuobo slammed the table, so angry that he shouldn't say anything.

"Boss, boss, don't be angry, don't be angry." Wang Genji shivered with fright, and quickly calmed down, "Boss, I assure you, within a week, it will definitely be done."

Jiang Shuobo's expression was unmoved, he just stared straight at Wang Genji.

Wang Genji felt a little flustered.

"Basically, I heard that your paper was included in the sci journal, don't you want to celebrate?" Zhuang Poxiao reminded me.

"Oh, yes, yes, yes!" Wang Genji slapped his thigh, and said to Jiang Shuobo with a smile, "Senior, and Breaking Dawn, student Cheng Nuo, then we will entertain you tonight and celebrate. By the way, I will apologize to everyone. ."

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

"no problem."

"can."

"I'm free!"

Hearing the words "Seafood Dinner", the eyes of the three people lit up at the same time. Nodding in agreement.

Jiang Shuobo patted Wang Genji's shoulder, "Gundu, you are also a member of our team. It is okay to understand each other. Even if this matter is exposed like this, you should face it together if you have any difficulties and hurry up. It’s still too late."

Wang Genji was slightly moved.

Jiang Shuobo pretended to be indifferent and added an understatement, "By the way, don't forget the treat tonight. I heard that there is a seafood restaurant near the school, which is very delicious, or let's go there."

Wang Genji: "..."

"Okay... OK. Senior, listen to you."

…………

The dinner party 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 slowly said, "Dawn and I have not been idle during the period of your two research topics."

"For the content of the next three parts of the subject, we have almost figured out the detailed steps. Only when the basic results come out, we can start work."

"But..." Jiang Shuobo's words turned, his tone was slightly worried, "However, when we were doing the detailed steps, a more serious problem emerged."

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

"Senior Jiang said, it should be this." Cheng Nuo, who had been looking down at the a4 paper Jiang Shuobo handed over, pointed to a line of text.

That is a detailed step in the fifth part of the paper.

That is, by what method, the experiment of substituting numerical values ​​into the final research results.

Jiang Shuobo nodded, glanced at Cheng Nuo, and slowly said, "Yes, it's here."

"According to our previous thoughts, this part can be performed by manual calculations or by copying calculations with a calculator to perform numerical substitution experiments. However, after careful study, this is not the case."

"It's also my fault. The algorithm that is finally solved by the preprocessing system is too simple. That level of complexity, coupled with the huge amount of calculation, is not something we can calculate manually."

"So?" Cheng Nuo said.

"So, we can only use mat1ab to do the fifth step of the numerical substitution experiment!"

"Mat1ab?"

The name Cheng Nuo has been heard.

mat1ab is an advanced technical computing language and interactive environment mathematics software for algorithm development, data visualization, data analysis and numerical calculation ~www.readwn.com~ Many data processing and image rendering in the field of mathematics, all Need to use this software.

However, for college students, the depths have not yet been reached, so this software is rarely used.

"Yes." Jiang Shuobo nodded, "The current situation is that we have to use mat1ab to get the final step of the subject."

"So I want to ask you two, would you use mat1ab to program?" Jiang Shuobo naturally asked Cheng Nuo and Wang Genji.

The two shook their heads together.

"That's no way. Daxiao and I don't understand this knowledge." Jiang Shuobo smiled bitterly and shook his head.

Learning mat1ab programming, the difficulty and time spent, is actually similar to learning a net language.

They don't have time to learn software that may not be used in a university every four years.

Therefore, the current situation is a bit difficult.

Jiang Shuobo said, "Oh, it seems that I can only ask the classmates at the Academy of Planning if they will meet."

"Senior Jiang, it doesn't really need to be so troublesome."

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

Jiang Shuobo looked at the source of the sound, "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 said earlier that he did not know how to program mat1ab.

"No, you can learn!" Cheng Nuo smiled lightly. "Give me a week, enough!"

Cheng Nuo wanted to say that giving him a day would be completely fine.

But that seems too crazy.

Then... a week!
