We can also calculate distance using another way to measure the size of the vector by effectively adding all the components of the vector and this is called the Manhattan distance a.k.a L1 norm. These vector norms treat an m×nmatrix as a vector of size m·n, and use one of the familiar vector norms. For example, using the p-norm for vectors, we get: kAk p = Xm i=1 Xn j=1 |a ij|p 1/p. The special case p= 2 is the Frobenius norm, and p= ∞ yields the maximum norm. Larisa Beilina Lecture 3

The Euclidean distance tools describe each cell's relationship to a source or a set of sources based on the straight-line distance. There are three Euclidean tools: Euclidean Distance gives the distance from each cell in the raster to the closest source. Example of usage: What is the distance to the closest town? For any induced norm ∥·∥, the identity matrix In for Rn×n satisfies ∥In∥ = 1: (8) However, for the Frobenius norm ∥In∥F = √ n; thus it is not an induced norm for any vector norm.

This example illustrates how to compute the Euclidean Norm in R using the norm() function and the type argument. To calculate the Euclidean Norm, we have to set the type argument to be equal to “2” within the norm function. The explanation for this can be found in the help documentation of the norm function: type = “2” “specifies the “spectral” or 2-norm, which is the largest singular value (svd) of x”.
