Mathematically a norm is a total size or length of all vectors in a vector space or matrices. For simplicity, we can say that the higher the norm is, the bigger the (value in) matrix or vector is. Norm may come in many forms and many names, including these popular name:Euclidean dist...

As a by product, a fast loop-free error-free vector transformation is given. That transforms a vector such that the sum remains unchanged but the condition number of the sum multiplies with the rounding error unit.doi:10.1007/s13160-023-00593-8Siegfried M. Rump...

Dividing a vector by its norm results in a unit vector, i.e., a vector of length 1. These vectors are usually denoted s→^ (Eq. 7.1)F→^=F→║F║ An exception to this rule is the basis vectors of the coordinate systems that are usually simply denoted e→…. Basic vectors of ...
