For MIMO systems, this quantity is the peak gain over all frequencies and all input directions, which corresponds to the peak value of the largest singular value of sys. For more information, see hinfnorm Robust Control Toolbox. Compute the H 2 norm of the transfer function. The H 2 norm is the root-mean-square of the impulse response of sys.

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. Calculate the 2-norm of a vector corresponding to the point 2,2,2 in 3-D space. The 2-norm is equal to the Euclidean length of the vector, 1 2. As an alternative, you can use the norm function to calculate the 2-norm of the entire matrix.

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.

The 1 -norm of an m -by- n matrix A is defined as follows:. Edited: James Tursa on 21 Sep Toggle Main Navigation. If A is a vector, then vecnorm returns the norm of the vector. If A is a multidimensional array, then vecnorm returns the norm along the first array dimension whose size does not equal 1. See Also cond equationsToMatrix inv linsolve rank. The Frobenius norm of an l -by- m -by- n multidimensional array X is defined as follows:. See Also. Create two vectors representing the x,y coordinates for two points on the Euclidean plane. Vote 1.
