Find in matlab

Help Center Help Center. If X is a vector, then find returns a vector with the same orientation as X. If X find in matlab a multidimensional array, then find returns a column vector of the linear indices of the result.

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 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.

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.

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.

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. In this example, we have a vector [1, 2, 0, 4, 0, 6]. The find function is applied to identify the indices of non-zero elements, which are then displayed.

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.

Look for the last n nonzero elements in X using find X,n,'last'. You can use the logical and , or , and not operators to apply any number of conditions to an array; the number of conditions is not limited to one or two. Other MathWorks country sites are not optimized for visits from your location. Finally, find the elements in A that are less than 9 and even numbered and not equal to 2. Change Language. What kind of Experience do you want to share? Find the nonzero elements in a 3-by-3 matrix. Together, row and col specify the X row,col subscripts corresponding to the nonzero elements in X. Replace all values in A that are greater than 10 with the number Examples collapse all Zero and Nonzero Elements in Matrix. This will find all indices of all non-zero elements present in the array and store them into the vector v.
