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.

Help Center Help Center. When you want to access selected elements of an array, use indexing. There are two ways to refer to a particular element in an array. The most common way is to specify row and column subscripts, such as. Less common, but sometimes useful, is to use a single subscript that traverses down each column in order:. Using a single subscript to refer to a particular element in an array is called linear indexing. If you try to refer to elements outside an array on the right side of an assignment statement, MATLAB throws an error.

For this, we can use the following syntax of the "find" function. What exactly is a "fractional index"? Print Page Previous Next. Walter Roberson on 15 Jan The sub2ind and ind2sub functions are useful in converting between subscripts and linear indices.
