 ### Methodes
 
-- __init__(self, l: list[list[complex]]=[]) -> None
+- ```__init__(self, l: list[list[complex]]=[]) -> None```
 
   initiates the matrix
 
-- __mul__(self, __value: "Matrix") -> Matrix
+- ```__mul__(self, __value: "Matrix") -> Matrix```
 
   defines the natural multiplication as the Koeneger product for matrices
 
-- __apply(self, x: list[complex]) -> list[complex]
+- ```__apply(self, x: list[complex]) -> list[complex]```
 
   takes a list to represent a vector in a colonne, and return the proctuct of the matrix by this vector
