dot R Documentation
Scalar Product
Description
'dot' or 'scalar' product of vectors or pairwise columns of matrices.
Usage
dot(x, y)
Arguments
x
numeric vector or matrix
y
numeric vector or matrix
Details
Returns the 'dot' or 'scalar' product of vectors or columns of matrices.
Two vectors must be of same length, two matrices must be of
the same size.
If x and y are column or row vectors, their dot product
will be computed as if they were simple vectors.
Value
A scalar or vector of length the number of columns of x and
y.

Examples
dot(1:5, 1:5) #=> 55
# Length of space diagonal in 3-dim- cube:
sqrt(dot(c(1,1,1), c(1,1,1))) #=> 1.732051
