Ji Ran returned to bed, slept a lot, and when he opened his eyes again, he couldn't help but be startled, it was already seven fifty o'clock.

Ji Ran hurriedly got up and hurried to school without even closing the door.

When Ji Ran came to the school, the teachers were already standing on the podium.

Ji Ran embarrassedly made a report, and the old professor pushed the heavy glasses under the wine bottle, said come in, and then began to continue the lecture.

Ji Ran returned to her seat, but saw Chen Lili drawing her eyebrows and eyes, as if she was very excited.

"Lily, what are you doing? Are you going on a blind date? Ji Ran looked at Chen Lili and asked.

"Xiao Ji Ji, you should also dress up, there is a lobby class of the little Han male god today." Chen Lili said excitedly.

"Little Han male god? Who? Ji Ran asked strangely.

"You're not, aren't you? Don't you even know Brother Xiaohan, the most handsome male god teacher in our School of Information? Chen Lili looked at Ji Ran as if she was looking at a monster and asked.

Ji Ran blinked strangely, and after thinking about it carefully, it seemed that he was a little impressed, it seemed that there was really a very handsome male teacher in the Information School of S University, I had seen him on campus before, he was super good and super handsome, however, he didn't teach Ji Ran here, although he was in the same college, but, after all, the majors were different, so Ji Ran didn't know much about the handsome male teacher.

"Today there is a lobby class of the little Han male god, let's go together." Chen Lili said excitedly.

"Didn't he teach us, what are we going to do?" Ji Ran asked strangely.

"Oh, of course I'm going to see a handsome guy, Teacher Xiaohan is so handsome, so temperamental, and he is already a teaching assistant at a young age, I like him so much." Chen Lili said, her two eyes were about to be heartbroken, and she looked like a nymphomaniac.

"Do you like Ma Kai or Teacher Xiaohan?" Ji Ran asked with a headache.

"Of course I like both, but if I want to say I like it more, of course it's Mr. Xiaohan, it's just that Mr. Xiaohan is so high-end and high-end, I'm afraid that I won't be worthy of him, I feel that Ma Kai is more reliable." Chen Lili thought for a while and said.

Ji Ran looked at Chen Lili, smiled and shook her head, I don't know if she is stepping on two boats?

The old professor's lectures are boring and tasteless, and I will fall asleep when I listen to them, in fact, the old professor is still quite knowledgeable, but unfortunately, he is too serious when he lectures, and the tone is not shocking, which makes people feel drowsy after listening to it for a while.

Before Ji Ran knew it, he slept in two classes, and his saliva almost flowed out.

When the bell rang for the end of class, Ji Ran suddenly came over, it turned out that he was in class just now?

"Little Ji Ji, let's go, hurry up and occupy a seat, there will be no more if you go late." After class, Chen Lili dragged Ji Ran to the big class.

The large classroom can accommodate nearly 1,000 people, the reason why the big classroom is to improve the efficiency of teaching, in fact, to put it bluntly, is to save trouble for the teacher, if there is no lobby class, the teacher wants to lecture class by class, if his major has 5 classes, then he has to teach five classes.

And after having a big class, you can let all the students of five classes come to a big class, so that you can talk about five classes in one class, and it is not difficult to go up to the fifth floor in one breath.

Of course, for the lobby class, the students naturally have no objection, because during the lobby class, the teacher basically does not check the number of students.

When the time comes, students who want to skip class can rest assured that they can skip class, anyway, there are a few fewer students, and the teacher can't see it, even if you come to every class, the teacher may not remember you.

As a result, some hall classes should have two or three hundred people, but there are often dozens of them, and some hall classes are obviously only about 100 people, but they are full, and the difference is that it depends on the teacher's personal charm.

Generally, the number of students in the lobby class is directly related to the appearance of the teacher.

The better the teacher, the higher the full attendance rate of the lobby class, and if it is the lobby class of the old professor, I am afraid that it will not be so popular.

Ji Ran followed Chen Lili to the big classroom, found the front row of seats, and sat down.

"Lily, why are you sitting so close? We are not in this major, how bad is it to be discovered by the teacher? Ji Ran still felt a little embarrassed about the behavior of skipping class.

Although it is a common behavior to skip classes in school, even if you skip classes, they will not ask you to overcharge tuition, but, after all, it still encroaches on other people's classroom resources.

"Don't worry, it's going to be fine, I've been here many times." Chen Lili said with a smile, as if she was quite experienced.

Soon after, many students came to the class, and most of them were girls, even girls from other colleges, and even a few girls from the archaeology department.

"Oh my God, the archaeology department is coming to listen to MATLAB? Do they understand? Ji Ran asked strangely.

"Those old antiques are just like us, they are all here to see handsome guys." Chen Lili said with a smile.

"We don't have textbooks." Ji Ran looked at the classmates around him, most of them were holding professional textbooks, but Ji Ran and Chen Lili actually came empty-handed, and they didn't even bring a pen, which looked so embarrassing.

"Don't worry about it, we just need to listen to the lecture of the little Han male god." Chen Lili said indifferently, anyway, she didn't care what the male god was talking about, just so that she could have close contact with the male god teacher in class, and look at him more, if he could smile at himself, then he would be happy all day.

The huge class was soon full, and Teacher Xiaohan also stepped onto the podium under the expectant eyes of many students.

"So lively? Full again? Teacher Xiaohan smiled humorously, and everyone laughed along.

After Mr. Xiaohan made a brief opening remark, he went straight to the topic.

Some people say that MATLAB will not have children except for others, although this sentence is a bit exaggerated, but there is also a certain amount of truth, if mathematica is a sniper rifle in the mathematical world to overcome difficulties, then our MATLAB is a super arsenal in the mathematical world.

MATLAB is extremely powerful, with a rich algorithm toolbox, which can realize matrix operation, data visualization, GUI processing, and even connect to other programming languages, so it can be seen everywhere in engineering computing, control design, signal processing and communication, image processing, signal detection, financial modeling design and analysis, and other fields..."

Mr. Xiaohan used a magnetic voice to passionately explain his MATLAB course on the podium, and the students under the podium all sat up straight and listened to his lecture with interest.
