[Numpy-discussion] Vectorization of the product of several matrices ?

Hello and thank you for your answer.

The lists would be made of 4x4 matrices :
LM = [M_i, i=1..N], M_i 4x4 matrix
LN = [N_i, i=1..N], N_i 4x4 matrix.

N would be 1000 or more (why not 100000... if the computation is not too long)

Thank you for this one. I am curious about other possibilities.

And also : is there a document about how the python interpreter works ? (order of the operations, typical timings, ...)

Regards,

O.C.
