Different norm of a matrix

WebMatrix or vector norm. This function is able to return one of eight different matrix norms, or one of an infinite number of vector norms (described below), depending on the value of the ord parameter. For tensors with rank different from 1 or 2, only ord=None is supported. Parameters: a array_like. Input array. WebDefinition 6.1 (Vector Norms and Distance Metrics) A Norm, or distance metric, is a function that takes a vector as input and returns a scalar quantity (\(f: \Re^n \to \Re\)).A vector norm is typically denoted by two vertical bars surrounding the input vector, \(\ \bo{x}\ \), to signify that it is not just any function, but one that satisfies the following criteria:
