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 find in matlab that meet the given condition. It returns a vector that contains the linear indices.

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.

Help Center Help Center. This example shows how to filter the elements of an array by applying conditions to 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. You can perform these tasks using a combination of the relational and logical operators. To apply a single condition, start by creating a 5-by-5 matrix that contains random integers between 1 and Reset the random number generator to the default state for reproducibility. Store the result in B. The result is a logical matrix. For example, A 1,1 is 13 , so B 1,1 is logical 0 false. However, A 1,2 is 2 , so B 1,2 is logical 1 true. Rather than comparing the two matrices element by element, you can use B to index into A.

Help Center Help Center. If X is a vector, then find returns a vector with the same orientation as X. 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.

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.

The result is a column vector of linear indices. Help Center Help Center. Example 1: Below code will return the indices of non-zero elements in a 1-D array. Sometimes it is useful to simultaneously change the values of several existing array elements. Suggest changes. Article Tags :. However, A 1,2 is 2 , so B 1,2 is logical 1 true. Share your thoughts in the comments. Note: If the array contains duplicates then find X function will return all the indices of that integer. Output Arguments collapse all k — Indices to nonzero elements vector. The result, 8, is even, less than 9, and not equal to 2. Statistics Cheat Sheet. Share your suggestions to enhance the article.
