+## Matrix
+
+Matrix(l: list[list[complexe]])
+
+- 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
+
+### Methodes
+
+- __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]
+
+  takes a list to represent a vector in a colonne, and return the proctuct of the matrix by this vector
