MATLAB provides a handy function called find to simplify locating the index of a specific value within an array. It returns the indices of the elements that satisfy a given condition. Here, array is the input array, value is the specific value you want to find, and indices is the resulting array containing the indices where the specified value occurs. In this example, we have an array [2, 3, 1, 2] , and we use the find function to locate the indices where the value is equal to 2. The result is stored in the variable indices. Here, we modify the condition inside the find function to identify indices where elements are greater than 1. The find function is not limited to arrays; it works seamlessly with matrices. In this example, we have a matrix with two rows and two columns. We use the find function to locate the row and column indices where the value is equal to 2. The find function in MATLAB provides an efficient way to locate the indices of specific values within arrays or matrices.

Matlab find index of value in array

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.

This is clear! The only drawbacks are the reuirement that you know how many dimensions. To find array elements that meet a condition, use find in conjunction with a relational expression. Share your thoughts in the comments. You can return the nonzero values in X using X k. Ran in:. I'm guessing this is what you mean. Toggle Main Navigation. MathWorks Answers Support.

If the direction is first it will return first n indices of that corresponding element or if the direction is last it will return the indices by traversing from the end of the array.

Whenever I've wanted to find the index of a specific value I subtract the value of the element I want then take the min of the abs of that.
