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 the first five elements that are less than 10 in a 4-by-4 magic square matrix. For instance, find the element equal to 13 in a 1-by vector of odd integers.

You can use indexing to access the elements of the array. To find the index of the element in the array, you can use the find function. Using the find function you can find the indices and the element from the array. The find function returns a vector containing the data. Note: If the array contains duplicates then find X function will return all the indices of that integer. When the array contains duplicate values the find function will print all the indices of that corresponding element. You can also find the index of the elements from both directions in the array. Both directions mean from starting and from last by using find X,n,Direction. This function find n indices in X according to the Direction. If the direction is first it will return first n indices of that corresponding element or if the direction is last it will return the indices by traversing from the end of the array. This will find all indices of all non-zero elements present in the array and store them into the vector v. Skip to content. Change Language. Open In App. Improve Improve.

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. Note: k will be of same orientation as X if X is a vector and if X is a multidimensional array then k will be a column vector which will hold linear indices.

Find the first five elements that are less than 10 in a 4-by-4 magic square matrix. For instance, find the element equal to 13 in a 1-by vector of odd integers. To find a noninteger value, use a tolerance value based on your data. Otherwise, the result is sometimes an empty matrix due to floating-point roundoff error. Create a 6-by-6 magic square matrix with all of the odd-indexed elements equal to zero.

MATLAB, a powerful numerical computing environment, offers a plethora of functions to manipulate, analyze, and visualize data. Among these functions, the find function stands out as a versatile tool for locating the indices of non-zero elements within arrays and matrices. It is a versatile function that can be applied to vectors, matrices, and multidimensional arrays. For vectors, a column vector indices is returned, containing the indices of non-zero elements. For matrices, two vectors, i and j , can be returned, representing row and column indices, respectively.

You have a modified version of this example. Number of nonzeros to find, specified as a positive integer scalar. Create Improvement. The result is a column vector of the elements in A that are less than 9. Off-Canvas Navigation Menu Toggle. The relational expression can be used in conjunction with find to find the indices of elements that meet the given condition. By default, find X,n looks for the first n nonzero elements in X. Using liner index a multidimensional array can be accessed using a single subscript. This example shows how to filter the elements of an array by applying conditions to the array. A linear index allows use of a single subscript to index into an array, such as A k. Like Article. Usage notes and limitations: X must be a tall column vector.

The linear index changes depending on the size of the array; A 5 returns a differently located element for a 3-by-3 matrix than it does for a 4-by-4 matrix. Complete Tutorials. Similar Reads. Main Content. Find the first five elements that are less than 10 in a 4-by-4 magic square matrix. Note: If the array contains duplicates then find X function will return all the indices of that integer.
