Find matlab

Funkcji, bez której można się najczęściej świetnie obyć, z czego wiele osób nie zdaje sobie sprawy. Rozważmy następujący problem: W wektorze danych chcemy znaleźć element o największej wartości. Po jego zidentyfikowaniu należy usunąć go ze zbioru. Jak to zrobić? W zasadzie intuicyjnie narzuca się tutaj wykorzystanie funkcji max. Niestety intuicja nie podpowiada zazwyczaj, jak zrobić to w prawidłowy sposób. Pozostało nam więc wyszukanie, w którym miejscu wektora v znajduje się element m. Można to zrobić w ten sposób, jednak nie ma to większego sensu. Indeks elementu potrafi wskazać nam funkcja max , należy tylko postarać się o zapisanie drugiego argumentu wyjściowego, jaki zwraca funkcja. Co w przypadku, gdy nie szukamy wartości maksymalnej ani minimalnej, jak w takim przypadku można obyć się bez funkcji find?

If X is a multidimensional array, then find returns a column vector of the linear indices of the result. The default for direction is 'first' , which finds the first n indices corresponding to nonzero elements. Use the logical not operator on X to locate the zeros.

Find matlab

The find function in MATLAB is used to find the indices and values of non-zero elements or the elements which satisfy a given condition. The relational expression can be used in conjunction with find to find the indices of elements that meet the given condition. It returns a vector that contains the linear indices. Using liner index a multidimensional array can be accessed using a single subscript. MATLAB treats the array as a single column vector with each column appended to the bottom of the previous column.

Tags stepinfo step response. The way to fix that is to figure out why suma has less than i elements, and then fix the problem. Trial software. Why the values of these times are the same, even though they are on different place on the time axis? Index exceeds the number of array elements. These times were different, even though it was that same plant. Support Answers MathWorks. Can you show the code you are using to reproduce the issue you are facing? Dave B. Search MathWorks.
