Hi all,

I am looking for a function like cumprod() that works for matrix
multiplication.

In other words, I have matrices [M1, M2, ..., Mn], and I want to calculate
[M1, M1%*%M2, M1%*%M2%*%M3, ..., M1%*%...%*%Mn] as quickly as possible.
Right now I'm using a for() loop but it seems like there should be a faster
way.

Any help is appreciated!

Thanks,
