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, find in matlab. The relational expression can be used in conjunction with find to find the indices of elements that meet the given condition.

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.

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.

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.

Add Other Experiences. Easy Normal Medium Hard Expert. Even when you provide the output vector k , the output is not fixed-size because the output can contain fewer than k elements. A linear index allows use of a single subscript to index into an array, such as A k. 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. Skip to content. Please Login to comment Vote for difficulty :. Open In App. No, overwrite the modified version Yes. Usage notes and limitations: X must be a tall column vector. Since B is a logical matrix, this operation is called logical indexing. Suggest changes.

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.

You can suggest the changes for now and it will be under the article's discussion tab. Interview Experiences. Specify three outputs to return the row subscripts, column subscripts, and element values. Toggle Main Navigation.

Otherwise, the size is 0-by Example 2: Below code will return the first 2 indices of elements where the element will be greater than 3. 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. For example, find x,1 returns a variable-length vector with one or zero elements.
