Find the treasures in matlab central and discover how the community can help you. Using length is a really bad idea. To directly find the elements in x that satisfy the condition x 5 use x x 5 avoid function calls like x find x 5 which unnecessarily use find on a logical matrix. You can use the find function to return the positions corresponding to an array element value.

You can perform these tasks using a combination of the relational and logical operators. 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. Generally to generate a multidimensional array we first create a two dimensional array and extend it. To find array elements that meet a condition use find in conjunction with a relational expression.

You can perform these tasks using a combination of the relational and logical operators. 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. 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.

In python i can use. Store the row and column return from find and put it in the match cell array. 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. 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.

The linear index of 5 is 4 not 5. For example find x 5 returns the linear indices to the elements in x that are less than 5. I know that number for example 5 is an element in array x but i don t know it s index. Multidimensional arrays in matlab are an extension of the normal two dimensional matrix.

A 7 8 8 2 5 6. An array having more than two dimensions is called a multidimensional array in matlab.
