The valid values of p and what they return depend on whether the first input to norm is a matrix or vector, as shown in the table. Shift array circularly matlab circshift mathworks france. In an assignment ai b, the number of elements in b and i must be the same. This matlab function returns the euclidean norm of vector v.
The padding input inherits the data type of the vec input. Gpu arrays accelerate code by running on a graphics processing unit gpu using parallel computing toolbox. If a is a vector, then vecnorm returns the norm of the vector. Ce tutoriel contient les bases permettant lutilisation du logiciel matlab dans. When the input argument is a string array, the double function treats each element as the representation of a floatingpoint value. Pour chaque pdf, le premier argument est lensemble des donnees, les. If k is a vector of integers, then each element of k indicates the shift amount in the corresponding dimension of a. If a is a multidimensional array, then vecnorm returns the norm along the first array dimension whose size does not equal 1.
Because symbolic variables are assumed to be complex by default, the norm can contain unresolved calls to conj and abs. Les dimensions dune matrice ou dun vecteur peuvent. Y circshifta,k circularly shifts the elements in array a by k positions. If padding has fewer elements than what the function needs to complete the last row of mat, then the function repeats the last element of padding until mat is full.
