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

Methode

• __init__(l: list[list[complex]]=[]) -> None

  initiates the matrix

• __mul__(__value: "Matrix") -> Matrix

  defines the natural multiplication as the Koeneger product for matrices

• __apply(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

• __str__() -> str

  returns a string representation of the matrix

Staticmethods

• I() -> Matrix

  returns the matrix

\begin{pmatrix}
1 & 0\\
0 & 1
\end{pmatrix}

• H() -> Matrix

  returns the matrix

\begin{pmatrix}
\frac1\sqrt 2 & \frac1\sqrt 2\\
\frax1\sqrt 2 & -\frac1\sqrt 2
\end{pmatrix}
