basic_unit

---

squ_tex.py

Contains two classes: SquTex and SquTexSlide

---

SquTex

A data block, inheriting from :class:~.VGroup,

• Commonly used for demonstrations of data structures and binary encoding,
• Combines squares and numbers together, supporting unified and individual animations,
• The distance member records the gap between data when first constructed,
• Single animations can be created using :method:animate_one_by_one to group animations,
• When creating the data block, all modifiable parameters are passed to the :class:~.Square class,
• To modify other parameters, use :method:change_square and :method:change_text,
• Be cautious when using :method:change_text, as it will change the hierarchy of the original object,
• Use :method:add_bracket to add brackets to all negative numbers in the data block.

Usage example:

from manim import *
from yty_manim.basic_unit.squ_tex import SquTex

class SquTexCreate(Scene):
    def construct(self):
        t = SquTex("rainbow")
        self.play(t.animate_one_by_one(FadeIn , scale=1.5))
        self.wait()

---

SquTexSlide

A sliding data block, inheriting from :class:~.SquTex,

• Adds sliding animation to the data block,
• Use :method:slide for basic positional sliding,
• Use :method:slide_fade for internal or external sliding with smooth fade-in and fade-out for the data block.

Usage example:

from manim import *
from yty_manim.basic_unit.squ_tex import SquTexSlide

class SquTexSlideBasic(Scene):
    def construct(self):
        s = SquTexSlide("rainbow")
        self.add(s)
        self.wait()
        for i in range(len(s)):
            self.play(*s.slide(-1))
        self.wait()

---

dec_bin.py

Contains a class BinNumber

• Currently no interfaces for other animations, improvements planned during the winter break.

---

BinNumber

A data block for binary numbers,

• Records the sign bit, integer part, and fractional part of a binary number,

• Converts decimal numbers to an ideal binary format,

• Can perform operations on binary numbers.

• Initialize with empty values for the object, then use :method:bin2dec to convert the binary object to a decimal number,

• Use :method:standardize to standardize the binary number format,

• Use :method:ex_one to convert to its one's complement,

• Use :method:ex_two to convert to its two's complement,

• Use :method:information to display all parameter information,

• Use :method:cal_check to check if precision will be exceeded during calculations,

• Operator overloading methods follow the format of the first operand.

Usage example:

from yty_manim.basic_unit.dec_bin import BinNumber

# Define decimal number and convert it to binary
test_bin = BinNumber(-0.2, 8, 1, True)
print(test_bin)
print(test_bin.ex_one())
print(test_bin.ex_two())

application

---

matrix_yty.py

Contains base class MatrixCal and actual computations MatrixDet and MatrixMath

---

MatrixCal

A matrix class for absolute control of matrix elements, inheriting from :class:~.VGroup,

• Commonly used for demonstrating matrix computations,
• Supports generating matrices with negative numbers and brackets using :method:neg_with_brackets,
• Get matrix rows using :method:get_row,
• Get matrix columns using :method:get_column.

---

MatrixDet

Determinant calculation, inheriting from :class:~.MatrixCal,

• Commonly used for demonstrating determinant calculations,
• Supports extended determinant calculation demonstrations using :method:det_mat,
• Automatically adjusts size using :method:set_scale_fitness,
• Get calculation process information using :method:get_process_inform,
• Get result information using :method:get_result_inform,
• Generate calculation steps using :method:cal_progress_times,
• Generate result steps using :method:cal_result_addition.

---

MatrixMath

Matrix operations, inheriting from :class:~.MatrixCal,

• Used for demonstrating matrix operations,
• Supports extended matrix operation demonstrations using :method:det_mat,
• Automatically adjusts size using :method:set_scale_fitness,
• Get operation process information using :method:get_process_inform,
• Get result information using :method:get_result_inform,
• Generate operation steps using :method:cal_progress_times,
• Generate result steps using :method:cal_result_addition.
