Multiplicação de Matrizes

• Branch segundo argumento:

  Python Listing: ../../Code/Matrix.py. def __mul__(A,B): ## Matrix mul: Branches over type of second argument, B: if (B.__class__.__name__ in [ 'int','float' ]): #Scalar: Return Matrix, return A.__mul_Scalar__(B) if (B.__class__.__name__ in [ 'Vector' ]): #Vector: Return Vector, return A.__mul_Vector__(B) if (B.__class__.__name__ in [ 'Matrix' ]): #Matrix: Return Matrix return A.__mul_Matrix__(B) print "Matrix.mul: Invalid second argument type",B exit()

  • Escalar;
  • Vetor;
  • Matriz.
• Scalar or Vector como Primeiro argumento [; c \underline{\underline{A}};] e [; \underline{v}^T \underline{\underline{A}};]

  Python Listing: ../../Code/Matrix.py. def __rmul__(A,B): return A.__mul__(B)
