Find A Value In An Array Matlab

Using length is a really bad idea.

Find a value in an array matlab. This example shows how to filter the elements of an array by applying conditions to the array. The linear index of 5 is 4 not 5. Store the row and column return from find and put it in the match cell array. You can perform these tasks using a combination of the relational and logical operators.

Generally to generate a multidimensional array we first create a two dimensional array and extend it. Linearindices find a 8 linearindices 2 3. Ismember will return an array of 1 or 0 depending on if the cell value there is or isn t the value you re searching for. For example find x 5 returns the linear indices to the elements in x that are less than 5.

Octave 9 x x 2 2 3 4 3 2 6 4 8 octave 10 ismember x 4 ans 0 1 0 0 0 1 0 0 0 and then you can use find and ind2sub to get the array indicies of the 1s. You can perform these tasks using a combination of the relational and logical operators. For instance you can examine the even elements in a matrix find the location of all 0s in a multidimensional array or replace nan values in data. But if you want to extract row and column you just need to adapt the code jan gave you.

For instance you can examine the even elements in a matrix find the location of all 0s in a multidimensional array or replace nan values in data. This example shows how to filter the elements of an array by applying conditions to the array. For example let s create a two dimensional array a. A 7 8 8 2 5 6.

Find the treasures in matlab central and discover how the community can help you. I know that number for example 5 is an element in array x but i don t know it s index. In python i can use. An array having more than two dimensions is called a multidimensional array in matlab.

You can use the find function to return the positions corresponding to an array element value. Whoever wrote that template has done a lot of beginners a disservice by teaching them to use a function that would be better replaced by numel or size in this case numel would be much better and would actually loop over all elements of the input array.
