It computes the length or size of a vector or matrix and provides a measure of its magnitude or scale.If used with a vector, norm() returns the Euclidean norm, also known as the 2-norm, which calculates the square root of the sum of the squares of all the elements in the vector. By default, it is computed for column vectors.
