Find in matlab

Help Center Help Center. This example shows how to filter the elements of an array by applying conditions to the array.

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.

Find in 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. 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. Example 1: Below code will return the indices of non-zero elements in a 1-D array. Example 2: Below code will return the first 2 indices of elements where the element will be greater than 3. Example 3: Below code will return the last 2 row and column indices of elements that are greater than 3. So, A 2, 3 and A 3, 3 are the last elements that are greater than 3. We got 2, 3 and 3, 3 as output not 3,2 and 3, 3 because MATLAB treats the array as a single column vector with each column appended to the bottom of the previous column. Example 4: Below code will return indices of all the zero elements. Skip to content. Change Language. Open In App.

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. To find a noninteger value, use a tolerance value based on your data.

This limitation does not apply when the input is scalar or is a variable-length row vector. Current difficulty :. You can suggest the changes for now and it will be under the article's discussion tab. You can perform these tasks using a combination of the relational and logical operators. Be sure to specify each condition with a separate statement connected by a logical operator. Search MathWorks. Input array, specified as a scalar, vector, matrix, or multidimensional array. Last Several Nonzero Elements. You can use indexing to access the elements of the array. Using the find function you can find the indices and the element from the array. 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. The result is a list of all even elements in A that are less than 9. Contribute your expertise and make a difference in the GeeksforGeeks portal. Enhance the article with your expertise.

To find the index of the element in the array, you can use the find function. Please Login to comment You have a modified version of this example. Each index describes the location of an element in A that is less than 9, so in practice A I returns the same result as A B. Easy Normal Medium Hard Expert. You can reference the A 2,2 element with A 5 , and the A 2,3 element with A 8. A linear index allows use of a single subscript to index into an array, such as A k.
