Find indices and values of nonzero elements. If X is a multidimensional array, then find returns a column vector of the linear indices of the result. k = find(X,n,direction), where direction is 'last', finds the last n indices corresponding to nonzero elements in X.

Nov 1, 2022 · 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.

To find array elements that meet a condition, use find in conjunction with a relational expression. For example, find(X<5) returns the linear indices to the elements in X that are less than 5. To directly find the elements in X that satisfy the condition X<5, use X(X<5).

Sep 21, 2016 · Write each of your conditions as separate logical arrays. When you need to index, combine those individual conditions with and, or, not, etc.

Feb 14, 2024 · The find() function in MATLAB is used to locate the indices of non-zero elements in an array or matrix. It is a versatile function that can be applied to vectors, matrices, and multidimensional arrays.

Jul 4, 2021 · MATLAB provides functionality that finds the indices and values of all non-zero elements in a vector or multidimensional array; the find() function. The find function with required parameters gives back a vector containing indices of non-zero elements in the passed array/vector. Syntax: vec = [] %so

find. Find indices and values of nonzero elements. Syntax. k = find(x) [i,j] = find(X) [i,j,v] = find(X) Description. k = find(X) returns the indices of the array X that point to nonzero elements. If none is found, find returns an empty matrix. [i,j] = find(X) returns the row and column indices of the nonzero entries in the matrix X. This is ...

Mar 24, 2023 · MATLAB provides its user with a basket of functions, in this article we will understand a powerful function called ‘Find’. In its simplest form, find function will return the indices of array X that points to the nonzero elements. If it finds none, the …

Dec 27, 2023 · In this guide, you‘ve explored common applications and examples of harnessing MATLAB‘s find() function to search arrays, filter data based on conditions, extract multidimensional indices, identify non-empty cells in cell arrays, and related techniques.

Mar 28, 2017 · In the below code, We have a random population with structures Position (3D array) and Cost. I need to check whether a particular element present in the population If it does then I want to remove it from the population. I'm using 'find' function for doing it. It was working fine with arrays but with structures I'm getting error below error.
