Edit: renamed variables to match the names used in the. If M is too large, it might be faster, to iterate the rows of M and compare every row with your vector. X is your row: function ind findRow (M,X) tmp M - repmat (X,size (M,1),1) ind find (tmp,1) end. You can also define conditions for a matrix inside the find function. It is only suitable, if M (your matrix) is not very large, ie. In the output, the value 8 is present at index two inside the matrix. For example, let’s find the index of a value inside a matrix using the find() function. For example, in a 2-by-2 matrix, the first two indices lie on the first column, and the other two lie on the second column. If we only want to find a single index of the value inside a matrix, we can also find that, but we have to keep in mind that the elements inside the matrix are placed column-wise. In the output, the value 8 lies at the second row and first column. Output: MyVect = 1 2 5 8 12 16 row = 2 col = 1 For example, let’s create a matrix and find the row number and column number of a specific value using the find function. The result contains logical 1 ( true) only where both matrices contain nonzero values. Inside a matrix, the values are placed on rows and columns, and we can use the find() function to find the position of an element. There are two values greater than five and less than ten in the output, and their indices are stored inside the variable index. Output: MyVect = 1 2 5 6 8 12 16 index = 4 5 For example, let’s define a vector and find the values greater than five and less than 10. We can define it inside the find function using the greater than and less than operators. For example, if we want to find the index of values greater than one and less than ten. We can also define conditions inside the find function. In the output, the value 5 is present at index three inside the vector. We can do that by entering the value inside the find function and an equal sign, and the find function will return the index of that value.įor example, let’s define a vector and find the index of a specific value inside the vector. For example, consider we have a vector that contains numbers, and we want to find the index of a certain value.

To find the index of any value present in a vector using, we have to pass the value inside the find function. There are five elements but only four indices in the output because there is an element with zero value. Output: MyVect = 1 2 5 6 0 indices = 1 2 3 4 For example, let’s find the indices of non-zero elements in a vector. The find() function finds values and indices of non-zero elements in a vector or matrix. This tutorial will discuss the find() function in Matlab.
