I understand that the Product
is by default interpreted as the Product of function.
However, I need to use a similar function, but for matrices, and I wonder if Mathematica has something like that.
I know that I can make some programming code to achieve this, however, I prefer something like the Product function applied to matrices. (I have the index ‘i’ within the matrix)
Many thanks for any help,
Domingo
I am probably misunderstanding, but there is a form of product that takes multiple iterators:
Product[f, {i, 1, 3}, {j, 1, 3}]
If that’s not what you’re looking for, can you clarify your question? Maybe provide an example?
I’m not aware of one that is indexed like Product, but you can build the list of matrices easily with Table:
test = Table[{{x, a, x + i}, {a, b, a}, {b, a, a}}, {i, 1, 3}]
Dot and Times both take an arbitrarily long list of arguments:
Dot @@ test
or
Times @@ test
Thanks,
However, two lines of programming code are similar to or even simpler than using Table[].
Actually, I was looking for something indexed like Product Π.
Anyway, many thanks for your help.
