Multiple operations on list
Hello,
suppose I have a list with matrices:
a=list(x1=matrix(rnorm(10),5,2),x2=matrix(rnorm(10),5,2),x3=matrix(rnorm(10),5,2))
I want to compute for all combination of xi and xj (x1,x2 x1,x3 and x2,x3)
a value.
This value is given for the pair x1,x2 by trace(x1%*%t(x1)%*%x2%*%t(x2)) /
trace(x1%*%t(x1))*trace(x2%*%t(x2))
I know that product matrices t(xi)%*%xi can be obtained by:
