- l: representation of the matrix in a list

### Attributes

- ```__m: list[list[complexe]]```

  the values contained in the matrix.

- ```__size: tuple[int, int]```

  the size of the matrix

### Methode

- ```__init__(self, l: list[list[complex]]=[]) -> None```

  initiates the matrix

- ```__mul__(self, __value: "Matrix") -> Matrix```

  defines the natural multiplication as the Koeneger product for matrices

- ```__apply(self, x: list[complex]) -> list[complex]```
