Parallel scalar products
Computes scalar products of datasets of vectors or vectorial quantities.
scalar(x,y) ## Default S3 method: scalar(x,y)
x |
a vector or a matrix with rows considered as vectors |
y |
a vector or a matrix with rows considered as vectors |
The scalar product of two vectors is defined as:
scalar(x,y):= ∑(x_iy_i)
a numerical vector containing the scalar products of the vectors given
by x and y. If both x and y contain more than one
vector the function uses parallel operation like it would happen with
an ordinary product of vectors.
