dotProd computes the inner (or dot/scalar) product between two
norm2 computes the squared 2-norm of all the elements in a matrix or
If the vectors are of unequal length
dotProd will give a warning and

##Create two vectors of equal length v1 <- rnorm(10) v2 <- rnorm(10) ##compute the inner product between the vectors dotProd(v1,v2) ##or sum(v1*v2) ##compute the square 2-norm of v1 norm2(v1) ##or dotProd(v1,v1) ##or sum(v1*v1) ##If the vectors are of unequal length the longer vector ##gets truncated (with a warning). dotProd(v1,c(v2,2))
