Calculate the distance between two points as the norm of the difference between the vector elements. Create two vectors representing the x,y coordinates for two points on the Euclidean plane. Geometrically, the distance between the points is equal to the magnitude of the vector that extends from one point to the other. Calculate the Frobenius norm of a 4-D array X , which is equivalent to the 2-norm of the column vector X :.

Compute the 2-norm of the inverse of the 3-by-3 magic square A. Compute the norm of [x y] and simplify the result. Because symbolic scalar variables are assumed to be complex by default, the calls to abs do not simplify. Assume x and y are real, and repeat the calculation. Now, the result is simplified. Remove assumptions on x for further calculations. For details, see Use Assumptions on Symbolic Variables. Compute the 1-norm, Frobenius norm, and infinity norm of the inverse of the 3-by-3 magic square A. Compute the infinity norm, negative infinity norm, and Frobenius norm of V. Input vector, specified as a vector of symbolic scalar variables, symbolic matrix variable, function, or matrix function that represents a vector.

Geometrisch ist der Abstand zwischen den Punkten gleich dem Betrag des Vektors, der sich vom einen Punkt zum anderen erstreckt. Input Array Eingabearray , angegeben als Matrix oder Array. Bei Berechnungen der Frobeniusnorm kann X ein Array sein. Normtyp, angegeben als 2 Standard , ein positiver reeller Skalar, Inf oder -Inf. In der Regel gilt Folgendes:. Verwenden Sie vecnorm , um eine Matrix oder ein Array als Sammlung von Vektoren zu behandeln und die Norm entlang einer angegebenen Dimension zu berechnen. Beispielsweise kann vecnorm die Norm jeder Spalte in einer Matrix berechnen.

If A is a multidimensional array, then vecnorm returns the norm along the first array dimension whose size does not equal 1. The size of this dimension reduces to 1 while the sizes of all other dimensions remain the same.

By convention, vecnorm returns NaN values if the vector being operated on contains a NaN value. Compute the norm of [x y] and simplify the result. See Also. However, the two results might differ slightly due to floating-point round-off error. This function fully supports thread-based environments. The Frobenius norm of an m -by- n matrix A is defined as follows:. Select a Web Site Choose a web site to get translated content where available and see local events and offers.
