Example

Code

# folder/file: tut/manim_mobject_matrix_001a.py

from manimlib.scene.scene import Scene
from manimlib.mobject.matrix import Matrix

class manim_mobject_matrix_001a(Scene): 
    def construct(self):
        num=Matrix(["1234555","1.0","0"])
        self.add(num.move_to([0,1,0]))
        self.wait(2)
        self.add(Matrix([(0,1,5),(3,4.5,5)]).move_to([3.5,3,0]))
        self.wait(2)
